In 1974, Dr. Henry Heimlich published findings on what was to become the Heimlich Maneuver. A week later, the first choking victim was saved by the method. In 1978, New York City passed a law requiring that every establishment, regardless of size or design, “where food is sold and space is designated specifically as eating areas shall have posted in a conspicuous place, easily accessible to all employees and customers, a sign graphically depicting the Heimlich Maneuver or a comparable technique instructing on how to dislodge food from a choking person.” The bill was passed unanimously by the City Council in 1978 (five days before Christmas and its feasts.)

Take a closer look at this poster:

I can just see this scenario play out at The Spotted Pig:

Asian Lady: "That's it!" (throws napkin down) "I just can't take it anymore!" (choking noises)
White Lady: Lady! Hey lady! Chill out! You're going to be ok! You have so much to live for!" (taking her tenderly from behind) ... i love you...
Asian Lady: "aaahhhhhghhghhghahgghhgurglegurgle"
Is this poster a "how to" for the Heimlich or is it really an expertly disguised PSA for the Suicide Hotline?
