vintage scratch & sniff fruit scented stickers, peach & strawberry good work reward

Lot of vintage (90s?) fruity scented stickers, peach and strawberry, as shown. Never used, though there's one strawberry missing from one sheet. Nineteen strawberries, thirty-two peaches.

I always think of these as 'scratch and sniff' stickers, but these have a noticeable scent even without scratching. Which is kind of amazing since I think they're about 30 years old, or maybe more.
