The GrafixJoker is the creative brand of Joe Maracic, and name on his social media profiles. The profile pic used is his goalie mask from the 90’s, that he painted in Boston.
While in art school, he played hockey, and continued throughout the years in NY. His teammates called him “Joker”. Maybe he was funny or something? Then later, coworkers added the Grafix part.
Now you know.
