Postcard Set: Springs and Rivers
Six Archive Postcards of Florida's water, as a set: Rock Springs at Apopka, the entrance to Silver Springs, the electric glass bottom boats, Wakulla Springs with its herons, a tarpon on the line off Fort Myers, and the wood stork and egret rookery in the newly opened Everglades National Park. All are public-domain Tichnor Brothers linen cards from the 1930s and 40s, reprinted full-bleed at 4 x 6 inches on heavy matte stock with a plain writing side.
