Marblehead Pottery Piece # 340 Shape 8 derived, Possible Tea jar, Blue, Undecorated, Pottery is 3 & 1/2 Inches High , Impressed MP Ship Mark , eBay 6/17/2011 ( Bluesnwhites) “Here's a wonderful original Marblehead Pottery covered piece, which I believe may have been designed as a tea jar. It measures just about 4" high and is done in a great blue glaze. It is in EXCELLENT condition. The bottom shows the 3 kiln marks & one is a little larger than normal. This is NOT a chip & definitely occurred in the making. The silver cover is unmarked and has a ding and minor wear but nothing that detracts from the beauty if this rare little gem!!” Piece 339 Piece 341
