For sale is the bottom piece to a Royal Copenhagen Blue Fluted Half Lace butter dish (I do not have the lid).  This is a pretty rare item in this pattern, and it is signed and numbered (1/502) on the bottom.  The base measures about 6 1/2" wide by about 1 3/4" high, and there are no issues at all to point out, condition-wise.  This item would love to find a buyer that has the lid portion!
