The U.S. Postal Service has issued new “forever” stamps featuring vintage seed packets.

The stamps depict 10 images of antique seed packets originally printed between 1910 and 1920. Each has blossoms of flowers — cosmos, digitalis, primroses, calendula, asters, pinks (dianthus), linum, alyssum, phlox and zinnias.

Art director Antonio Alcalá used photographs of actual seed packets that were created using chromolithography — a process that replaced hand-tinted lithographs and allowed for inexpensive multi-color prints.
