I have studied, collected, and written about rock concert-posters for many years. I personally photographer some 33,000 major posters, measured them, and created a database of all their details. Said to be the largest database of posters in the world, I have donated complete sets of that data to the Bently Historical Library at the University of Michigan in Ann Arbor, the site ClassicPosters.com, and a new non-profit building soon to be opening on Haight Street in San Francisco. Hopefully some of these articles will be useful to those interested in the topic.
