“Imprint of Toppan, Carpenter, & Co., Philad. & New York. India paper only, mounted on new card. Top center, seated carpenter. Lower left, Columbus as we invented him (looks like a Flemish painter). Lower right, Franklin. Rare bank with only some proofs known from a few series. India paper toned and some flaws. The added card protects the paper integrity.”
