The University has also made available their Magic Posters and Playbills Collection. This collection contains several Houdini playbills, including a rare 1890s advert for Harry and Bess giving a full-on "Spiritualistic Entertainment" (busted).
Both these collections were previously only available online for a fee (free for students). The University of Texas acquired their vast collection of Houdini memorabilia and magic material in 1958.
Our friend Tom Interval at Houdini Museum has done a great job breaking down the collection and providing links and descriptions of all the scrapbooks and individual posters. Click on over to Tom's site or the Ransom Center to have a browse of these Houdini treasures.
