This just in from Jim Korkis:

[Above are two Disneyland postcards from the long defunct Art Corner at Disneyland. The cats from "Lady and the Tramp" postcard is from the mid-Fifties. The Disney costume characters might be from the early Sixties. Disney postcards are a great archive of Disney history. I love Disneyland:The Nickel Tour by Gordon and Mumford and am sorry they didn't do a book for Walt Disney World. However, there is an excellent website that documents WDW postcards.]
