There are 5 in this series of mats made by Mary Mossop for her Grandmother Lily Louise Mossop for her wedding present. Framed by Brenda Dennis 1995.

They are wood frames which are exactly 29cm diameter or 11 1/2 inches and have an opening of 23cm or 9 inches. They are professionally framed with wire hangers and plate glass on the front.

I would accept an offer for all 5 frames
