Daredevils Playing Tennis on a Biplane

(Original Caption) Gladys Roy, who gets her fun out of doing unusual things with airplanes, also likes to play tennis. Ivan Unger (member of the "Flying Black Hats") is her opponent. Frank Tomac is the pilot who keeps the plane at 3,000 feet. The only problem with this match is trying to retrieve a ball after it has bounced off the wing of the plane and plunged a few thousand feet.
