Triskaidekaphobia is the fear of the number 13. Paraskavedekatriaphobia is the fear of Friday the 13th. I have to admit I've always had a slight aversion to the number 13. Today's illustration was done for a magazine article on the subject of the phobia surrounding Friday the 13th. When I drew this, I tried to mimic the style of a 1950s magazine cartoon. The man was drawn by hand with pen and ink. The typography and coloring was done in Photoshop. And to my fellow Triskaidekaphobics out there, take it easy. It's just a number.
