It is special peice of female wrestling history no less.
It is, I believe, from an "underground" fem wrestling club in the San Francisco bay area back in 60's or 70's.
There are a number of vids of it around, every contest is har dfought between real amateur women Al trianed but not at BJJJ experrt level so good, old mat grappling to
the end.
Several martches had a female ref. The location might be tracable by some clever person de to eh unusual curved roof. An old ex Military building perhaps?
Another good match in that location here
