In this graphic essay, as funny as it is rigorously researched, writer Erell Hannah and illustrator Fred Cham plunge readers into the history of our perceptions of posteriors, questioning the construction of aesthetic norms through changes in society, from crinoline dresses to the popularity of the mirrored armoire, all the way to social media. Were we obsessed with rear ends when mirrors didn’t exist? Do we view the beauty of men’s and women’s buttocks differently? Why are men obsessed with women’s bottoms? Is cellulite an illness? Why is it so rare in men?
