Perhaps this clip is of the main event at Madison Square Garden, as filmed on September 15, 1937 and released by Paramount News. There is narration but the sound track is broken up at times... Stuff deteriorates... as does the wrestling.
Jack Curley was dead by the time this match was booked and filmed, and Von Zuppe's real name is given as Carl von Lehman. Professor Marconi may be a takeoff on the legendary Italian inventor; I don't know. The clip was released to several thousand theaters and a question I have is whether there's more burlesque here than wrestling.
Economically, times are still terrible with The Great Depression taking its toll on everything from farmers to factory workers (unemployment is at a real level of about 25 percent of the entire workforce of the U.S.). Thousands of New Yorkers are sleeping in shacks (called Hoovervilles) in Central Park (not kidding).
Sporting events are suffering in every format; baseball is hurting with empty ballparks and wrestling is bleeding though it's too early for blading to become a popular thing.
(Despite problems with the Sherman Grinberg web site, the company's deal with Getty Images to sub-license its footage seems to be going strong. The film is often NOT identical to what the Grinberg Starchive had so-far digitized and made public.)
