Gorgeous porcelain butter dish. (and/or cheese dish). This is likely a Lefton copy of an RS Prussia item. The bottom does have a red wreath mark with RS, but it does not say 'Prussia', and this is somewhat heavier than an RS Prussia porcelain item would be. The mark is shown in the RS Prussia book as not being a real RS mark, and the book on RS Prussia indicates that Lefton China Co. may have made copies of RS Prussia items. If you want an RS Prussia cheese dish, expect to pay around $650 & up! No chips or cracks and is 8.5 long x 7 wide x 4 tall. A gorgeous item that you can actually use since it is not RS Prussia! It would make a great housewarming gift! Price is firm.
