This was given to Disney Imagineers. It is round with a white background and shows Mickey dressed as the Sorcerer. Written around the edge is "Walt Disney Imagineering". It may or may not have, at one time, been a gift to Imagineers, however it was most definitely SOLD at "Mickey's of Glendale", which is the Imagineering Cast-Member Store. This Pin has since been retired & replaced with pin #2404. It measures 7/8" diameter. Back of the pin reads: asi/77340 with what "appears" to be a Heart underneath that. Similar pin #30552.
