Old school is right. The woman on the left is model Helen O'Connel and the woman on the right is go go dancer Margie Alexander. The woman boob-smothering her opponent is open star Little Oral Annie Owens. The big busted blonde in the full nelson is Candy Samples who was in her fifties when she did this.

The amazing thing that this stuff was considered smut when it first came out. Now its hanging in avant-garde art galleries.
