In my Ephemera gallery, I have this image:
I scanned it years ago from the magazine Strange Things Are Happening, which was a short-lived publication from Phil Smee’s insanely great Bam Caruso record label. It was attached to an article about early SoCal punks The Weirdos. It never actually said if it was one of their flyers or posters.
Since Francky, Ellen and Linda want a better quality version of it, there’s the 300 dpi PNG linked above, plus a couple of vectorized versions I produced: World Full of Weirdos (PDF), World Full of Weirdos (EPS).
