What do Walt Whitman, Oscar Wilde, and Andy Warhol have in common? If you're thinking, "They were all gay," you're only half right. They're also all included in this amazing Great Gays Out of the Closet Mug. When the mug is empty, it shows fourteen closet doors. But when you pour in a hot beverage, 14 of the world's most famous gays proudly emerge. Holds 14 oz / 400mL. Disappearing mugs are not dishwasher safe but are microwave safe.
