This Mickey Mouse vinyl figure is released by Funko in their POP! Disney x Mickey and Friends vinyl figure series.
Funko POP! is a crossover vinyl figure series by Funko and other famous franchises such as Disney, Pixar, DC Comics, Marvel Comics, Simpsons, South Park, Uglydoll, etc. Each POP! figure is about ~3" to ~5" tall and crafted in a Japanese anime/manga super-deformed style (NOTE: due to the unique design of each character, the actual size of the figures may be smaller or bigger than stated).
This series features characters from the Mickey Mouse universe, a fictional shared universe which is the setting for stories involving Disney cartoon characters Mickey and Minnie Mouse, Pluto, Goofy, and many other characters. The universe originated from the Mickey Mouse animated short films produced by Disney starting in 1928. Still, its first consistent version was created by Floyd Gottfredson in the Mickey Mouse newspaper comic strip. Real-world versions also exist in Disneyland and Tokyo Disneyland, called Mickey's Toontown. Collect them all!
