This is a cool variant to what I have in my collection. From about 1913 through 1932, German porcelain manufacturers - there were at least two different "factories" producing this kind of material - issued a dazzling array of Halloween-themed tea set pieces. The children's sized tea pot, lidded sugar bowl and creamer are perhaps the most common of the output. There is a wildly rare set of items made for the adult table. Not only are the sizes significantly larger, but the designs tended to be more complex. The item up for sale here is from this extremely hard-to-find adult-sized set of items. The one in my collection, shown on page 117, has an orange cat. Prior to seeing this listing, I was unaware that a variant featuring a black cat existed. I expect this item to bring quite a high price.
(And it brought just that, the very strong price of $576.99.)
