If you haven’t kept up with Blink-182’s outstanding drummer Travis Barker or watched the “What’s My Age Again?” video, you should know that he is a tattoo enthusiast. And not merely in the manner that many individuals like getting tattoos: The 45-year-old’s tattoos (which cover over 70% of his body, according to GQ) constitute a perplexing riddle right out of a Dan Brown novel. He shows no indications of decelerating. Barker has received new tattoos now that he’s come back into the cultural limelight in a big manner, dating Kourtney Kardashian and producing for stars (like Lil Nas X). In Barker’s tattoos, there are amazing insights to be found. In his autobiography, Can I Say, he remarked, “They’re all recollections?” “They’re all things I’ve gone through.” While we can’t possibly cover them all (can anyone?), here’s a rundown of the most important Barker tattoos.

This one should go without saying. It’s also the title of his 2015 book, and it’s somewhat of a personal motto. In the book, Barker doesn’t hold back, discussing his plane disaster, the breakup of Blink-182, and his drug and s*x addiction. He’s gone through so much!

The race flag design on Barker’s neck is one of his most visible and long-lasting tattoos. According to Body Art Guru (it’s a thing), it represents the year of his favorite Cadillac in an interview.

Barker’s preferred vehicle brand is confirmed by a large “Cadillac” covering the side of his body. The drummer does, in fact, have a valuable Caddy collection.

Barker’s abdomen is stunning even without ink, but the large boombox in the middle, with a winged heavenly figure rising from above it, is difficult to ignore. Over the years, the so-called “ghetto blaster” has become a hallmark, and Barker said he’s seen a lot of followers imitate it on their own bodies.

Barker wants you to know he came from humble beginnings, as evidenced by the words “SELF” on one hand and “MADE” on the other. Blink-182’s record sales prove that he is a success.
