Cereal Lite Ups - Keep on Bikin' Sticker - Honeycomb cereal premium sticker - 1977
These are some fun cereal stickers that were available in boxes of Honeycomb cereal around the summer of 1977 - Star Wars time. Also, these were called "Lite Ups" flourescent stickers.
A similar series of sticker premiums were found two years earlier in boxes of Post Raisin Bran cereal, though they did have some differences.
As with many of these day-glo items, I've done some basic clean-up in Photoshop, to present them as closely to the original sticker as possible. Enjoy!
