No Smoking or No Pie?
Have you ever done an exercise to alter one line in a drawing to produce a different picture? You’ve never noticed that the “no smoking” symbol resembles a slice of pie with just one extra line! This graffiti artist performed something very similar on the “No Smoking” sign below.

The sign now forbids pies rather than smoking, which is considerably less appealing to me. I was thinking about a French silk pie or maybe a key lime… Of course, I won’t be eating it in an Ikea store since the sign specifies that it’s not permitted.
