Critics and censors have been debating for centuries over where to draw the line between porn and art. But don’t look for any answers in this new ad campaign from (who else?) American Apparel. Both of the graphite-pencil images, drawn by artist Boris Lopez (who is best known for his work in Hustler’s Barely Legal and Tight), feature a perky-nippled lady pulling off her panties. Tag line? “Cotton. You can feel how good it looks.” You’re welcome, cotton lobby.
