******The Jack Stewart Dissertation******
“An Aesthetic Study of Graffiti on the Subway System of New York City, 1970-1978″

This auction is for the ORIGINAL, one-of-a-kind, one and only, legendary dissertation by Jack Stewart.

You may be thinking “wait a minute that’s impossible”. You’d be thinking wrong because this is the real deal, the actual dissertation by Jack Stewart, photographer of graffiti from 1970-78.

This ultra rare item is considered to be the holy grail of early graffiti documentation. Hundreds of photographs, most of them have never been seen before except by a select few lucky people. Jack Stewart documented graffiti in NYC using 35mm cameras, talking with the early artists, and having the writers visit him at his studio. Many of the most famous graff writers visited his studio and Jack would show off the pics with a slide projector. Stewart worked on his dissertation for years, painstakingly pasting the actual photos into the pages of the book. He finally defended his dissertation in 1988 (NYU).

For those who don’t know about this work, it is considered the best ever documentation of early NYC graff, stuff that was BEFORE Chalfant’s Subway Art. In the beginning there was the first generation of NYC graff writers and Jack Stewart was there photographing their work. A rough count of the photos is approximately 400 different photos of trains with classic graff. This dissertation alone will make any graffiti collection one of the best. Photos in the dissertation span the range of the earliest graff to 1978.
