unmarked antique parian ware bisque china cordial cups, vintage celadon green

Set of eight tiny mugs, fine grained bisque china in a lovely palest green color.  We've been told these are cordial cups, with the cherries or hanging fruit. They're just 2 1/4" tall.

These are not marked, though we'd guess they might be German? We've never found Parian in a 'useful' piece before (although the cups have never been used, and frankly don't look as though they were made to really use at all). The color is uncommon, and we wish we could find out a little more about these pieces.

We do know that they came out of an estate of an antique dealer retired from the business for the last 20 years, out of the Milwaukee area.
