POLAND. Bank Polski. 10 Zlotych, 1928. P-67p. Presentation Book of Progress Proofs.
A wonderful presentation album that contains 13 individual progress proofs tipped into black heavy paper pages with a single loose card proof of just the primary face design. All others are banknote size on watermarked paper with various stages, but not all, of the printing process. Typed letter dated April 24, 1928 pasted inside of front cover. Certainly a great research item and also one that will add depth to any collection it enters. About Uncirculated.
Estimate: $750.00- $1500.00
