I pulled this from under a table at an estate sale on Saturday. There were actually two of them, I'm keeping one and selling one (in my current auctions). It's a mail-away Ralston Chex Cereal premium from the '50s "Space Patrol". There was a specific episode which had these Martian Totem Heads in it. The art and wording on the envelope are pretty cool, it has a Freaky-Tiki Mars thing going on...spiffy.
Check out the inside... ...and this:
