RARE Antique Fine White Cobalt Blue Gold Painted Porcelain Footed Scallop Handled Leech Jar. Unmarked, but numbered "278". 19th or 20th century. 5.5" x 5" x 8" (inches).
I believe it to be a leech jar as it is notable larger than the many porcelain or ceramic creamers that I have collected over the years.
