Guy Aitchison (born 1968) is an American tattoo artist and painter.

He is the brother of tattoo artist and television personality, Hannah Aitchison.

[8] Guy Aitchison was already in an apprenticeship at the Jacklich Corporation in the art department by age 17.

After completing his apprenticeship, he began painting record covers for Vinnie Moore, David Chastain, Apocrypha, Hex, Skatenigs, and mostly for California-based Shrapnel Records.

He opened his own tattoo studio, Guilty & Innocent Productions, which remained a top standing shop until 1998 when it shut down so that he could move to the country to focus more on painting.
