Tom of Finland, a cult illustrator. By day he crafted campaigns of happy heterosexual couples buying soft drinks and laundry detergent for advertising. By night, he was otherwise occupied. Bulging muscles. Throbbing members. Motorcycles. Gay pride. Any time a stylist puts a young pop star in a leather biker cap for a magazine shoot, the impact of Tom of Finland is not far-off. The iconic artworks are depicted on the recycled zip pockets.
