This offering is for a Great Celluloid Button. It measures 1 1/16". looks like a spider web to me. I believe it is made of celluloid. It is a sew through. It was hard to photograph, there was lots of glare. It could use a light cleaning, but I am leaving that up to the new owner. I have 6 of these buttons. This is a great button for your collection. Please see the other buttons that are listed also.
