In 1964 he was photographed by Dennis Hopper posing next to one of his works. For the occasion he wore a 60s mod staple, a turtleneck, along with light colored pants and a pair of used sneakers.
One of my favorite works from Lichtenstein is "In The Car" from 1963. Not only does it capture the style of that year, but it depicts a scene that reminds of Don & Betty Draper from "Mad Men".
