I've always wondered about this flea, but they hold it on Sunday mornings and I"m always in church. No flea for me. ( really bad rhymes I can do) 01:06 Schlock, at best factory art. Some of it done in the 60s is fun, but the recent stuff is only good for color on walls if you don't have much money or taste. Colorforms are not shrinky-dinks. IIRC they stick to a vinyl backing and you can make pictures with them. They're still produced. (do not heat them; they'll just melt into trash.)
Those 2 liter glass coke bottles were used up in Maine when they first adopted a bottle bill back in the mid -70's. You got a 10 cent refund on them. Used to see them in all Coke flavors when I vacationed in Maine back then.
Colorforms are like a vinyl paper doll were shrinkidinks are pieces of plastic that you color then put in an oven and they shrink down into a hard ornament
