(1970s) An infamous "World Fair" souvenir pocketknife featuring Mickey Mouse. These knives first appeared in the collector's market during the 1970s. However, the Mickey Mouse image is a more modern version than was used in 1933, and the "World's Fair" title is misspelled as "World Fair." Despite the unusual history of these knives, they are quite desirable among collectors and have earned a unique place in Disneyana history. Measuring 3.5" long when closed, the knife is in very good condition with minor wear from use.
