People just seem to love Jon Hamm. Superstardom has come to him fairly late in life and owes a lot to his success in 'Mad Men', but there's no denying his earthy, charismatic appeal. Women want to date him, and men think he's the kind of guy they'd love to go for a drink with. He appeals to everybody and has a relaxed character that puts people at ease as soon as he appears on screen. Very few people have that quality!
That might explain why someone decided to go the whole way with their Hamm love, and have a hyper-realistic tattoo of him on their arm. The details really pop out of this picture, capturing his good looks and his impeccable style perfectly. As a nice touch, what portrayal of his 'Mad Men' character would be complete without a whiskey on the rocks?
