Frame measures 4.5 by 4.5 inches.
Found this among some of my grandparents things. (They passed in 1981, both at the age of 83) I imagine it dates back to early 1900's
I also have listed separately a second frame that is exactly the same size and pattern Complete with the silhouette painting: "A FRESH TEAM". The frames match and seems as though they were sold as a pair. I have included a picture of the complete one along with this one listed, but I have listed that one as a different item.
Thank-you for your interest
