Earthbound Pizza Scratch and Sniff Keychain Promo

VGMM alerted me to this awhile back, but I never had the time to post it.

Apparently, this Promo Keychain was known about for sometime, but had never been officially confirmed to exist until this auction popped up with a lot of assorted Nintendo keychains. Supposedly this item is related to the Earthbound ruler and the mythical Mach pizza box, and may have been included in that press box, but also given away separately. It sold for $535.47, and you can bet all or at least the majority of that price was for the Earthbound one.
