A
car styling
gimmick which became compulsory on
American cars from
1955 to
1959. Invented by
General Motors'
Harley Earl and first appearing on the
1945 Cadillac.
The tallest fins belonged to the 1959 Cadillac but the longest fins were found on the 1958 Buick Limited. GMH also put some pretty nice fins on the FB and EK Holdens.
