Pietra dura ...

... Italian for 'hard stone'. Different colors of marble polished and glued together to form pictures. In this case unidentified birds. Well, maybe you can identify them ? 12 cm x 18 cm x 1 cm. Mahogany frame. The Italians made them and sold them to tourists, mainly in the 18th and 19th century. This one is believed to be from the late 19th century. I bought it at an Internet auction in competition with several bidders, so it got a bit expensive, that's life ... I hope you like it and have a Happy Easter !
