The Bunny Museum is the only museum and research library dedicated solely to collecting, preserving, researching, interpreting, and exhibiting bunny objects of value for enjoyment, understanding, and educating the public about bunnies throughout history through art, advertising, culture, film, literature, and propaganda. Now with over 43,000 objects—Guinness World Record-certified (1999, 2011)—this historical art museum opened in 1998 in Pasadena, CA, then moved to Altadena in 2017.
