Found design is always a delight. These signs are posted at some of the parks around Chicago, and though they look recently produced (not much wear from the weather, no rust, etc.), I believe the design is old, though I don't know.

Check out the dog, the leash, and the flower! It seems stylized in the right way to have come out of the early part of the last century, doesn't it?

I wonder who decided that a scrawny scotty was the way to go.

This is definitely one I'd like to have on the wall in my work-room.

Seeing it reminds me to look for the interesting/beautiful in the everyday, and of course to look for more cool signs!
