Sometimes described as "America's Greatest Rock and Roll Band," the "bad boys from Boston" have been going strong since 1970, though the period from 1979-1984 was a dark one, as the band wrestled with personnel changes and drug addiction. (That's probably when they got a lot of the tattoos.)
Although several band members have tattoos, Steven Tyler has the most well-known tattoo design: red flames with the words "Ma Kin" etched on his left bicep. Surprisingly, this is Tyler's only real tattoo. The musician enjoys covering his arms with other types of "temporary body art," as you can see in the photo, but it is drawn on with markers.
