Tidy folds and poker faces

Of course these guys don't like anyone poking around at the folds.

The pokers might discover the steel last-like frame that makes this

lovely illusion. It still requires a dedication to not moving that

most of us do not have.



I had never seen this particular bit of street art until my visit a

few weeks ago to Italy where I saw versions of it in all the tourist

areas. Reading up on the trick, I see that it's been used for a

century or more. This one was in Pisa.
