Since her inception in 1974, Hello Kitty’s cute yellow nose and large red bow has been placed on just about every kind of product imaginable—she’s even been on cans of motor oil! By 2014, Hello Kitty was worth an incredible 7 billion dollars! A special exhibition at the Japanese American National Museum celebrates 40 years of Hello Kitty’s worldwide influence with original artwork, fashion, and other rather unusual Hello Kitty swag.

Yuko Shimizu, Hello Kitty’s creator, drew inspiration from Lewis Carroll’s Through the Looking Glass focusing on Alice’s pet named “Kitty.” Some mystery surrounds Hello Kitty’s design and personality, like the fact that she was designed without a mouth and given little facial expression. Company spokespeople, however, say her lack of a mouth indicates universality, that the character speaks many languages, and that it means Hello Kitty desires worldwide friendship. With Hello Kitty merchandise available in over 60 countries, the emotionally aloof feline has certainly achieved her goal!
