“The human leg has evolved continually over many eons, adapting from an underwater propeller to its current form. But on book covers and on film and theater posters, the leg has evolved very little. In fact, the ‘A-Frame,’ a cutoff-torso-spread-leg framing device, is the most frequently copied trope ever used. From steamy paperbacks designed in the ’40s (Pamela’s Sweet Agony), hardly a year has gone by without at least one ham-fisted advertisement using this perspective.” (Thanks kottke.org!)
