The Great Moustaches Mug celebrates 14 of the world's most celebrated mustaches and the men that made them famous. The moustaches of Mark Twain, Lao Tzu, Leon Trotsky, and Groucho Marx are just some of the great mustaches featured on this cool and quirky mug. For extra fun, each moustache is numbered. Try to guess who each mustache belonged to, then check the bottom of the mug to find out if you're correct. (WARNING: make sure the mug is empty before turning upside down to check the bottom!) The ceramic 3 1/2 inch diameter, 12 ounce Great Moustaches Mug is microwave and dishwasher safe.
