It's the return of Operation M.O.U.S.E. Exclusively for Members of Disneyland's Magic Kingdom Club (a series post is coming soon on the MKC, really). January 1969 is the Month Of Unusual Savings in Entertainment.
Has anyone ever seen that "Mouse Money"? I think I passed one up years ago on EBay not knowing what it was! Good for 50¢ on food or merchandise or admission to any attraction, now I really want one!
Be sure and check out "Stuff from the Park's" blog post today (link) it features an "Inside Disneyland" from 1969 that has info on operation mouse! Thanks Matterhorn!
