The pedestrians aren’t walking under a ladder or in any danger of knocking the man from his perch. As you can see at right, the realistic-looking man and ladder are merely a painting.
This trompe l’oeil mural graces the exterior of Sign-Wize in Pomona at Park and Monterey, but it appears Sign-Wize itself is no more. (It may have relocated to Rancho Cucamonga.)
The painting of a man on a ladder adjusting a letter in a sign that no longer exists may not be long for this world, so I thought I’d better document it while I could.
