Anyway, I've often found random Boontonware pieces, even a few sets of plates, saucers and cups or the odd serving bowl but never such a complete set! Look at all the serving pieces!
These have been used, some of the plates have a little staining and the platters have a few utensil marks, but they are still serviceable and should remain so for many years.
In the early 1950s, the use of plastic dinnerware was so widespread that Consumer Reports Magazine tested and rated the workmanship, construction and design in its January 1951 issue. Of the 12 brands tested, Boontware was “judged superior to all others,” edging out competition from Texas Ware, Arrowhead Ever Ware and Watertown Lifetime Ware. The engineers at Consumers Union noted Boontonware’s “excellent resistance to chipping and breaking” along with its “excellent durability in washing.”
