On the back page, a Magoos fan could order a very cool looking iron-on transfer, join the Blue Magoos Society, and order a "wild" psyche-de-lite, the secret formula of which creates the "wildest, weirdest shapes imaginable!" We're informed that "it's so wild the BLUE MAGOOS carry two PSYCHE-DE-LITES with them everywhere they go." I know I want one. Of course you can, or could, find one on eBay.
Grab that lollipop and enjoy.
