WHOA! I don't think the kind folks at Woolworth's intended our little KOPEEFUN consumer to use this magic transfer paper to copy hot, pre-code comic babes! Maybe the older brother got into the pack?
Kopee was magic. All you had to do was rub! A tracing paper impregnated with some mysterious chemical which would allow you to lift images right off the pages of your comics! I think this is what the copyright statement means when they say not to be stored "in any retrieval system."
Carefully preserved in a package from 1941. As you can see, the manufacturer had numerous suggestions for use. Well...I'm just glad our little wicked rubber had "extra sheets"
