Vintage/Mid Century/Art Deco/Celtic Knot Aluminum Etched Bowl or small platter

This can be used for soooo many things!!! It’s approx 12” diameter. The etched design is similar to Celtic knot patterns. Circa 1940’s so a bit pre modern but has that MCM FEEL for sure! And from the 40’s so it also has an Art Deco feel as well! Similar to talavera aluminumtrays but at a fraction of the price of those!
