Circa 1950's, this is a group of heavy pottery, restaurantware creamers. 2 are white pottery, with black trim, and the other 2 are tan pottery. The tan creamers are 2&1/2 inches tall. The plain one is marked, "Syracuse China. The short, white creamer is 2&1/4 inches tall, and the taller is 3&1/4. Other than the one, there are no markings. This was common in restaurantware, as the bottom of the small creamers didn't have enough room for a mark. All are in excellent condition.
I currently have several pieces of restaurantware in my shop, including Wallace and Tepco, and am happy to combine shipping. To see them all, type, "restaurantware" in the search box at the top of this page.
