21.1¢ Envelopes Coil Stamp with ZIP+4 Mr. Zip GAMM Cachet
A Washington, D.C., first-day cover for the 21.1-cent Letters coil stamp (Scott 2150), issued October 22, 1985. Richard Sheaff designed its descending row of five colored envelopes; it was the first U.S. multicolor gravure coil. The denomination paid the minimum First-Class Mail rate for qualifying mailers who used ZIP+4, which had begun in 1983. Gerry Adlman's one-color GAMM cachet revives Mr. ZIP—the mascot created for the original five-digit ZIP campaign—with “ZIP+4 Tomorrow's Address” and “Regular Postage 21.1¢ Coil” text.
