The New York Public Library has restored a collection of magic posters that were developing problems because of how they had originally been pasted into a scrapbook that became unstable over time. There is a Houdini poster that experts have said is the only one known, as well as other rare items, including items relating to Thurston, Kellar, Dunninger, Albini, and numerous others. Many of the posters have been put into a free online database. I have a blog article that goes into considerable detail at: http://www.herbsmagic.com/magic-in-new-y......database

Thanks for posting that!
