"The Great Wm. P. Hall Shows"
Lured by the prospect of owning his own circus, Hall bought one in 1905 for $20,000 ($700,000 today). “The Great Wm P. Hall Shows - Double Menagerie - Colossal Circus - Elevated Stages and Real Roman Hippodrome” opened in Lancaster on May 6, 1905. This was a great boon for the county.
Hall was referred to as "Colonel Hall" for the first time in a July 1906 Billboard Magazine article. This article came out right after his circus opened. No one knows why, but the name stuck.

Hall's show ended in Lancaster that August, never to tour again. Although Hall loved the circus and loved to travel with his horse business, he greatly disliked traveling with his circus.
