Overprinting was done by the state printing house in Zagreb. It is known that only 10 denominations were returned into Split, other values (No. 8, 10, 11, 14, 15, 16 and 17) remained in Zagreb. So, we have a set with full version of 17 values (also called Zagreb version) and a subset version of 10 values (called Split version).
1943 Split local unreleased issue for Dalmatia, "Split version" of 10 values in blocks of sixteen. Complete set with the largest pieces that I know of.
