This auction, currently running on eBay, has a Jetsons cereal box from 1990 with a promotional ad offering a free trip to Space Camp.
The box is from 1990 (I didn’t even know there ever was a Jetsons cereal, let alone as recent as 1990).
The auction price is currently at $4.95. While I did plan to buy it so I could post scans of the back (assuming there’d be a full-blown Space Camp promo on it), I really can’t justify spending even five bucks for the thing, so you’ll have to make do with this very small picture the seller posted.
