This sign was created on a canvas type material, but it is linen. I put the design on a piece of wood, glued, to keep it sturdy to frame. It was done several years ago, and been in storage. It has a slight bend to the wood. You could leave it as is and create a hanger to hang. Or frame it, or put another back on it too.
It measures 15" x 18 3/4". The thickness is about 1/4" thick.
The condition is still in very good condition, with some mild staining, which the two close up pictures will indicate.
