While mindlessly perusing the Web, I found this video on www.Archive.org:
Description: This is a clip from a Universal Newsreel dated September 15, 1937. This clip features Dolores Gonzales and Clara Mortensen in a bout that took place September 1, 1937 in the San Antonio, Texas Walkathon arena. The referee is Dr. Karl Sarpolis, also a wrestler. This is the first professional female wrestling bout held in San Antonio. Clara won the match, but later faced Dolores again for a re-match because of claims that Sarpolis was an unfair ref.
Wow. There are some moves in here that would make even the most modern fan get off their feet. Check out the flip at the 1:25 mark and the spinning whatever-it-is that spills into the crowd at the 1:31.
