#46: So How Do You Feel about Philadelphia?
With this next image, there’s nothing inherently wrong with the original messaging; it just so happens that if you are standing in just the right spot, another sign interferes and gives viewers a rather insulting message about the intelligence of the residents of Pittsburgh. It’s just poor placing.

Or maybe it’s not so accidental. Maybe the designer of this store secretly hates Pittsburgh and secretly resented being forced to go there to decorate the store. With that in mind, she set up a very clever optical illusion so that when you stand in just the right spot, her true opinion of the city comes through. Or maybe it’s just a coincidence.
