1945 SPLIT, Overprint proofs

Split overprint proofs are very rare. Three full sheets and three half sheets [1] have been found long after the 1945. Over the last years, most of the sheets were cut and sold to the collectors. Only two half sheets remained whole and both are now with me.

Note that overprint plate with only half setting was used because base sheets were in tête-bêche orientation.

 1945 Split local provisional issue, overprint proof with value of 30 kn in darker green color, complete half sheet. Certificate Vilfan.

1945 ZAGREB, Overprint error

Stationery were overprinted with one phase in red color using setting composed with a bunch of different lines, five-pointed star, the inscription of a new state and a new nominal. Everything was fixed together quite well, so only minor displacements are recorded.

1945 Zagreb local provisional issue, stationery type Ib, with unusually large displacement of just one part of the overprint setting.

Such displacements have occurred because of loose cliches. Normal distance for a measure shown on the picture is 5.0 mm (type I) or 4.7 mm (type II and III).

1945 ZAGREB, Forerunner from Vinkovci

After the partisans takeover the continental part of Croatia and before the outcome of new stamps, payment in cash was used. In the first period the tariffs from the Split provisional issue were applied (10kn for stationery, 20kn for letter and 30kn for registration).

Note that such postal items sent from the continental Croatia (and especially from Srijem and Slavonija) are classified as forerunners of the 1945 Zagreb provisional issue.

Forerunner of the 1945 Zagreb provisional issue, registered letter sent from Vinkovci (29.V.45) to Stari Bečej - Bačka (31.V.45) via Beograd, properly charged of 50kn in cash (Split tariff: 20kn for letter and 30kn for registration), censored by the military censor in Vinkovci.

1943 ŠIBENIK, Hand overprints

It is not clear if 27 or 32 different Italian stamps were overprinted, however, it is known that most of them were done in a very small print run. For example: 1 Lire definitive stamp which exists in just 2 pieces. The rarest from my collection is 25 Cent air mail stamp that exists in just 116 pieces.

1943 Šibenik local provisional issue with N.D. / H. hand overprints. 17 values out of 32. Certificate Zrinjšćak.

HOWTO, Unhide content (again)

I have been asked about how I know what is the cancellation date on this letter. Frankly, I read it from the certificate :), but I could use some simple image processing tricks to find it by myself.

Original image - cancellation is poorly visible.

After some color hue & saturation changes I can clearly see 14.X.44.

1941 BANJA LUKA, Fakes

A few days ago, 1941 Banja Luka fake was sold on one of the eBay auctions...

eBay auction: 36 bids and a final price of 183.50$ shows that customers did not know it was a fake.


Genuine stamp from position 17 (left) and fake from the auction (right). Fake overprint is narrower and lower.


Checking just the first line - genuine (above) and fake (below) - the difference is apparent. See also details of "S", "b" and "d"...

1945 MOSTAR, Damaged stars

Damaged stars are common, especially those in the red color and on the values that were overprinted at the end. Probably the most damaged star is a star that you can find at Mi.5 Velebit at position 59.
          
Star from position 59, at the beginning and at the end of the overprinting process.

At the end of overprinting 44% of all stars have been damaged.

1945 GUŠTANJ, Cover

Immediately after the end of WWII the special canceller was used in Guštanj (german Gutenstein, now Ravne na Koroškem).

1945 Guštanj porto provisorium, official letter sent from Ljubljana (28.8.45) to Guštanj with arrival postage due stamps (30 pf Maribor local provisional issue and 0,50 din regular DFJ issue) cancelled with "Guštanj," / "PORTO".



Note that "Guštanj," ends with a comma. This is because it was used as a prefix for other cancellers, usually for "PORTO".

Type III is the most scarce of all types and subtypes of the 1945 Sarajevo provisional issue cards. Only a few are known.

HOWTO, Stamp Collecting Software

I just bought a new scanner and started to digitize my stamp collection. My goal is to create a database with each stamp individually. After one day of work, I can say that this will be very time consuming and tedious task. Unless I find a way to get myself 48 hours in a day, I need to do something to speed up this process.

Long time ago I worked on the development of image processing software, so I thought - maybe this will be a great opportunity to refresh my knowledge and have some fun too.

Let’s define our input as image with more or less randomly positioned stamps. 

Input image.

Step 1: Edge detection 

In theory, we know a number of edge detection filters, namely: homogeneity filter, difference filter, Sobel and Canny edge detection filter, etc. I decide to begin with the simplest one – the difference filter that finds edges by calculating the maximum difference between pixels in four directions around the processing pixel.

Edge detection - red line. 

Step 2: Quadrilaterals detection

Quadrilaterals (rectangles in our case) can be detected using Hough line transformation to find lines and then detect pairs of that lines that intersect with an angle of 90 degrees (approx.)

Quadrilaterals detection - yellow line.

Step 3: Extract individual item

Using quadrilaterals, we can calculate their bounding boxes and simply cut them out. All following steps are processed for all our cuts. 

Stamp extracted.

Step 4: Deskew (rotate) item

The rotation angle can be calculated from quadrilateral lines (as mean of all angles). Also Hough line transformation can be combined as a correction factor. In practice, getting angle is the most complicated operation in the whole process stack. But, when we have an angle, the rotation is trivial.

Stamp rotated.

Step 5: Fill background with transparent color

With last step we simply fill the background with transparent color. Flood fill algorithm is a way to go. Note that stamp image should be preserved in a format that supports transparency. My preferred format is PNG.

Stamp with transparent background.

I am now able to digitize my stamps for about fifty times faster! And, having images in such format brings a great deal of possibilities. Custom layouts are just one of them.
