Painting from the lobby of GCP....

I have one and it has a little metal tab glued to the back of tile that you can hang on a nail. no cardboard.

pinklemonade...never bought one but watched him sell them...it is for packaging purposes...it covers the tab that is used to hang the picture...sonofdob.

We bought two when we were there in January. Removed the cardboard and the tab was there.
