6 photographs of Warhol works.
One is a 1988 B&W photo of Warhol's 1964 Sixteen Jackies, part of a Death & Disaster exhibition of 35 works. This is a fine vintage photograph from the Houston Chronicle Library.
Another B&W photo is from 1990, showing Warhol's 1974 portrait of Frederick Weisman x 4. It was another newspaper archive photograph so there is limited marking on front.
The third photo is a B&W photograph showing Warhol's work, Suicide.
There is a small snapshot photo in purple tones of imagery we can't decipher, but might be a version of Car Crash.
Two color photos include one with a subtle drawing of a girl biting her finger or fingernail, offset by color swaths. The other appears to show a drawing? possibly of two men about to kiss, set in front of ... a Rorschach test pattern?
