Only three sheets of 160 kn / 0.50 kn were overprinted on pelure paper (plus one with inverted overprint). I found a really nice and unique corner side block of four.
1945 Zagreb local provisional issue, 160 kn / 0.50 kn on pelure paper, bottom left corner block of four. Max 75 exists. Cerificate Zrinjšćak.
