This is a single-sided, 1960's Grumbacher Artist Supplies sign. I believe it advertises a system that artists can use to stretch an unpainted canvas on a frame, prior to beginning a picture. This sign is single-sided and tin.. This colorful metal sign measures 8-1/2" by 24-1/2".

This 50-year-old sign is all-original and new-old-stock. It does have some minor marks in the blue background and a few small dents in the lower right corner from sitting around in storage all these years. I'm indicating this neat old sign is not perfect. So, please take a good look at the photo. Good color, and still displays nicely....especially for the money.

The price is just $45, plus the shipping.
