‘Cadillac Ranch‘ (1974) by Ant Farm.

Cadillac Ranch was installed near Amarillo, Texas, on Route 66. It consists of 10 Cadillac automobiles, representing a number of evolutions of the car line (most notably the birth and death of the defining feature of mid twentieth century Cadillacs; the tailfin) from 1949 to 1963, half-buried nose-first in the ground, at an angle corresponding to that of the Great Pyramid of Giza in Egypt.
