I'm not sure what it is. I took the back off and looked at it . The best way for me to describe it is like new money when you look at it from different angles it changes the coloring
I bought it
Thank you for submitting your item for appraisal. This appears to be a first half 20th century photogravure after the copper engraving by Sigmund Freudenberger (1745-1801) which he engraved after the painting by Nicolas de Launay (1739-1792) titled "LA GAIETÉ conjugale" (the happy family). This particular print was very popular, various later editions are known. The estimate is based on similar prints offered or sold at auction.
