THE BUMPY RAILROAD CROSSING AVOIDANCE MOTIVATOR

For its 1956 through 1958 product line, Chrysler Corporation offered as an option an under-dash record player.  It handled special 7" records which would play up to one hour per side (which was fairly impressive in an era where 7" 45 RPM records usually had only about three minutes per side).  The only company which made records which fit the player was Columbia.  For 1960 and 1961 Plymouths and De Sotos only, Chrysler tried again with an optional record player which would play a stack of up to fourteen standard 45 RPMs. Photo of 1960 De Soto Adventurer courtesy of Alf van Deem via Wikimedia
