I take a few days off and now I'm behind on Houdini stuff! The photo above is directly part of a piece covered by both John Cox and Kevin Connolly. The funny thing is I was going to hunt down stuff related to Houdini's film career and studio when I returned from Thanksgiving vacation. As soon as I get back I find both John and Kevin found something cool related to the topic. Please check out their links, the only thing I have to add is what that location looks like today via Google Earth. The current address is 216 19th St. Union City, NJ. The original address was listed as 216-222 Weehawken St West Hoboken NJ., it changed when Hoboken and Union City split up their areas.
UPDATE: Just got a better picture of the Warehouse. It is STILL standing! Compare it to the photo here
http://houdinihimself.com/?p=2234 It's the same building and it is still there after all those many years.
NEW UPDATE: Check out this development found at John Cox's site http://www.wildabouthoudini.com/2016/09/its-now-houdini-studio-in-new-jersey.html
