Just noticed this today on the subway:
Isn’t that weird? The Os are sideways, all of them. The N in lean is slightly shaved off on the right edge; compare it to the N in not. And the letters in lean don’t seem to have the same baseline.
What the hell is up with that? I thought it was some kind of pranked-up fake sign at first, but all of the Do not lean on door signs were like that.
Update: Here's a sharper photo on Gothamist earlier this year.
