Fun partial set of American Bank Note Co. Cinderellas/poster stamps - 1934

The American Bank Note Company (ABNC) produced a highly famous set of Cinderella stamps for the 1934 National Stamp Exhibition held at Rockefeller Center in New York. These were not valid for postage but were sold to collectors as souvenirs to demonstrate the company's superior engraving technology. We'll even include the original "Littleton Stamp Co." envelope.
