Wow! There is a very similar frame from an even older Superman comic that has Bizarro Lana tickling Bizarro Lois during a wrestling match. On the Bizarro world, the real Jimmy Olsen has been dispatched to cover a match between the two ladies. In one frame, Lois has her arms pinned above her head by Lana who is behind her. Holding Lois' arms with arm and hand Lana proceeds to tickle the helpless brunette under the arm with her free hand. Lana even describes the tactic as the "tickle hold". In that comic, both the women are wearing sleeveless garb and the frame shows Lana's extended forefinger in the hollow of Lois' armpit. Lana has an expression of wicked delight as Lois begs hysterically. Very hot and probably the first drawing I ever saw of F/F tickling. Are there other frames accompanying the one shown here?:lol
