Vintage MCM USA Art Pottery Leaf Dish 380 Set of 4 Turquoise Gold Speckle

Vintage MCM USA Art Pottery Leaf Dish 380 Set of 4 Turquoise Gold Speckle This is a set of four Mid-Century Modern style leaf shaped dishes. They are marked USA 380 but I don't know what company manufactured them. I am guessing they are from the 50's - 60's? They are pale turquoise with gold speckles and gold edges, and they have a glossy finish. These could be used as serving dishes, appetizer dishes, individual salads - there are lots of options. I also thought they might have been part of a Lazy Susan. They could also be used decoratively on a console, coffee table or shelf. One dish has a small chip on the underside of the rim - see photos 6 and 7. Another has a small pit - see photo 8. Otherwise, the dishes are in great vintage condition. Measure approximately 10.5" x 5.25" MCM, Mid Century Modern
