Unicorn on Rainbow (Kellogg's Fun Stamp/Cereal Promo Transfers/70's and 80's/Gay Pride)

Kellogg’s Fun Stamps — Promo Tee (1970s–1980s) Tiny ink transfers, cartoon mascots, and sugar-fueled breakfast-table chaos—Kellogg's Fun Stamps were peak childhood ephemera from the 1970s and ’80s. Packed into cereal boxes as mail-away prizes or box-back promotions, the stamps featured brightly colored artwork of mascots, animals, comics, and goofy characters meant to be pressed onto paper, notebooks, skin, or basically anything nearby. The graphics themselves captured the golden age of cereal-brand illustration: saturated colors, rounded typography, smiling characters, and the slightly surreal optimism of vintage supermarket marketing. Tony the Tiger, Toucan Sam, Dig ’Em, and countless forgotten mascots all existed in the same hyperactive visual universe.
