These classic Hello Kitty puffy stickers come from my childhood collection and are dated 1976.
I got these stickers as a "trade" during the early '80s sticker craze, and they have been in my sticker album ever since. I don't know what I traded to get them, but I'm sure I got the better deal, even with the missing flower sticker. Can you imagine kids occupying themselves with trading stickers and arranging them in albums nowadays?!
