What the heck is the poster on the left? Tenniel’s caterpillar? I know Dark Side of the Moon, Brain Salad Surgery and Aladdin Sane, but the first one stumps me.
I think I figured it out. I think it is a black & white version of the American Graffiti Movie poster.
By George, he’s got it!
I knew it looked familiar and then it took about 10 minutes of Googling. “1973 movie posters” got it.
