Beautiful old pressed pattern glass cake plate, circa 1900 vintage, sun purple lavender color.
This has surface scratching and utensil marks from years of use, and a slightly rough rim from fleabites. Sounds worse than it looks, this is a good piece of authentic antique glassware.
It measures about 10 1/4" across the rim of the plate, and about 9 3/4" inside the rim edge, so functional cake area is about 9" to 9 1/2" diameter.
