Grape, Joe St. Clair
These 5 1/4 inch blue plates (front and back shown) have fooled many a collector into thinking they've found a treasure. They're quite attractive but are not from the classic era. They sell for between $15 and $25.

Also in 2016, a red Grape & Cable tumbler, said to be by Joe St. Clair, sold for $15.
