Amid the vaults of sexual artifacts housed at the Kinsey Institute of Sex and Research in Bloomington, Indiana, there is a rather unorthodox diagram. Even the Institute doesnt know who made it, where or why it was donated to their collection anonymously and is loosely dated as 20th century. It depicts, in prudent detail, the precise way to administer a cane.

Atop the sketch of a womans backside (seen below), the artist specifies which regions of her rear are areas of maximum effectiveness, identifying them with shaded boxes. He or she also shrewdly points out that if the caner is left-handed, the directives should be reversed. It reads like an instruction manual for how to cane someone properly, curator Rebecca Fasman explained in a conversation with The Huffington Post. It looks so perfect, so professional, like something this person labored over for a while. They wanted to create a very clean guide to caning.
