This is a vintage ironstone restaurantware plate from Old Oaks Countryclub in NY. The Old Oaks Golf Logo is on the top of the platter. The back of the plate reads Sterling, USA. 
This plate is very heavy, and the red ticking stripe would be so pretty to add into an ironstone collection.
Measurements approximately: 13" x 9".
** There is a few minor imperfections in the glaze on the back of the plates which I took photos of so you can see it is spotty in a few places.
