Greenwood Car Show 2023 #4 - Tailfins "Tail fins started to appear on American cars in the late 1940s, and while many cars eventually adopted them, most experts credit Cadillac for introducing fins to the public. Although the fins served no practical purpose, they instantly connected Cadillac's luxury brand to the technological wonders that were capturing Americans' popular imagination at the time: rockets and jet airplanes." Most of my photos are of cars from the 60s.
