"Let It Be" in the top right corner: the artist had finished the drawing, gave it to me, but then decided to add "Let It Be" at the last minute. Nice little touch. :-)
The actual Beatles shirt has pictures of John, Paul, George, and Ringo, but the artist decided just to go with John for the sake of brevity, haha definitely a great job of doing John's face. :-)
My face! Ahhhhh run away! :-)
