This is beautiful white porcelain by the venerable Germany company Tirschenreuth. I inherited these pieces from my Austrian great aunt, and just don’t entertain the kind of company that would call for this level of classiness.
The serving platter is oval, with a cobalt band of color along the scalloped outer edge. 15" long and 10" wide.
The coffee pitcher is about 9" tall (to the top of the nub on the lid), with the same color cobalt ringing the top.
$50 for the set of two items.
