Alas, one such post went awry when the pictures I took of Mike's tattoos went AWOL on my computer, leaving me with a photo-less entry.
Mike has since sent me pictures, which I have included below.
On his right arm, he has this piece, which is an interpretation of Captain Marvel:
Mike explained that he collaborated with Ralph Velez at Venus Modern Body Arts in the East Village on this design. He told me, "I came up with a drawing and then he fixed [it] up so it would work on my arm ... this yellow is a mix he does himself...". He also credited Jhonson Eteng as the graphic artist for this tattoo.
and this Green Lantern/Blue Lantern combo on his arm:
As Mike puts it, he's "a big DC Comics fan".
