The museum's collection of circus artifacts is perhaps the largest in the world. It includes over 210 original wagons and vehicles once used by American, English and Irish circuses. It houses an exceptional collection of circus ads and posters. Over 9,500 multi-colored circus posters range in size from half-sheets to an 80-sheet Buffalo Bill Wild West poster which measures 9' high and 70' long. Thousands of journals, manuscripts and business records are available as well as original fine art oil paintings, hand bills, heralds, programs, artifacts of circus performers and a collection of rare photographs and negatives.
