The Butler County Historical Society is presenting its 11th annual “Butler of Yesteryear” calendar.

“Were You There ...” is loaded with photos and information from Butler’s Sesquicentennial Celebration and Parade in 1950.

See some of the marching bands, floats and parts of Butler’s 150th anniversary as well.

The full-sized calendars are available at the Butler County Historical Society office at the Senator Walter Lowrie House, 123 W. Diamond St., and at May’s Music Shoppe and Natili’s North.
