This just goes to show you that you can pretty much find anything for sale on Ebay.
This post from Dinosaur Dracula sparked my memory of these.
I only really wanted the Pink Lemonade carton(Pink Lemonade was my favorite, based on taste, and the look of the carton. Look at it!), but the auction, as it turns out, was for all four. They are pictured in the order of the years printed on their sides, starting with Grape from 1982, and ending with Orange from 1985. All four have gum inside, but I am not tempted to eat any of it. Well maybe I am just a bit curious to see if, at least the Pink Lemonade tastes the way I remember it.
