Highway Patrol

From the interweb we learn that this is a portrait of Trooper Clay W. Keith standing next to  his patrol car in Bartow, Florida.

Born on July 4, 1917 in Asheville, North Carolina. He was one of Florida's earliest troopers joining the FHP in 1941, a few years after it was officially established. He served 30 years in uniform, rising to the rank of major and becoming the state's first director of driver licensing in 1963. 

He left the FHP in 1978 to become the civilian head of driver licensing, and he remained in that post until retiring in 1987. In retirement, he became the official historian of the Florida Highway Patrol. Clay Keith died on December 18, 2000.

The automobile in the image appears to be a 1939-40 Ford Standard Tudor Sedan - commonly used by law enforcement agencies including the Florida Highway Patrol in the early 1940s.  

The rounded trunk and rear fenders are characteristic  of the 1940 Ford models .
