A 1934 magic kit officially licensed by Beatrice Houdini and Bernard Ernst has sold on eBay for $204. These kits are a nice early example of Houdini tie-in magic merchandise. I was fortunate to examine a few of these in the Arthur Moses collection during my recent Texas adventure. This particular kit was noted as being an "estate find."
Thanks to Kevin Connolly at Houdini Himself for the tip.
