I met the guy that invented color forms. He lives in NH. He made them on accident by solidifying wax at a cold temp. I don't think you can buy the paper stock. How about static cling on gloss card stock?
That's too funny. I met with this guy Don a couple years ago. He wanted me to produce banners for him for below the cost of the vinyl. haha.
He told me this story of how he incented color forms in the 1950's. Sold the rights to some other company, yadd-yadda-yadda.
I didn't research his story. Who would make up a story about color forms? Apparently this guy Don. hahahaha.
