I got these "Foldies" images from rob! over at The Aquaman Shrine, and needless to say they are more than a little weird. Way before my time, these guys (with art by Wally Wood!) were designed so that you could flip over the different panels in order to create strange mashups of characters. For example, you could put together the Hawkman top and the Cave Man bottom to make "Winged Cave Man," or Governor and Hawkgirl to make Dutch Hawkgirl.
As strange as some of these are, the entire set is so bizarre that I considered just making it a link post as a Weekly Dose of Weird over on The Bunker. Head on over to the Shrine and see the inanity for yourself.
