Kirk with a visual puzzle from my neighborhood. The image on the bottom is the actual photo and the image on the top is a mirror image of it (top and bottom reversed). As you can see, the English in blue only becomes completely legible in the mirror image. I’d love to know the backstory behind this (what the sign maker was thinking) but at this point I have no clue.
P.S. This apartment building is in my neighborhood. I’ve walked by it many times but only noticed the lettering being flipped vertically today.
