It's the circus queen and tinker bell Tiny Kline! While working for the Ringling Bros. and Barnum & Bailey Circus, Kline became well known for her signature "slide for life" stunt, an "iron jaw" act in which she slid to the ground while dangling from trapeze rigging by her teeth. Kline renewed her spectacular acrobatics at the age of seventy when she played Tinker Bell in the "Fantasy in the Sky" fireworks show at Disneyland.
Youtube user jonslick13, who uploaded the video says: "This is an actual filming in 1932 with a woman crossing Time Square , New York , hanging by her teeth. This is real and what I love is that she does an aerobic routine while she is hanging by her teeth; because hanging by her teeth 500 feet up might not be enticing enough. Awesome and will never be repeated". Commenter weirdiejohnson410 says: "tiny kline was my friend nora's great great aunt. so if anyone has any questions email ashleytisdale1207, and tell her hope told u to." Via Lars.
