I spotted this classic 1950's era black and white photograph from downtown Chicago at My Link page Northern California Bus Fans, located to the right of Your computer screen at www.norcalbusfans.com

Seen here at the old Trailway bus station on West Randolph Street near North Wabash Avenue in downtown Chicago, is a Cardinal Bus Company Flxible Clipper bus at the terminal, operating in Chicago area commuter bus service.
