VERY RARE CIVIL WAR GREAT CENTRAL SANITARY FAIR PROOF STAMPS

Rare opportunity here to purchase 3 more Civil War proof stamps from the Great Central Sanitary Fair. These proofs were printed to test the colors before deciding which color would be used on the 20-cent stamps. These are absolute gems, blank/no gum on the reverse as made. This is a very rare opportunity to purchase this set of sample/proof stamps. One price is for all three proofs.
