This is a doubly great item. The diminutive cup has a handle and the saucer is exceedingly rare. Although unmarked, these items are German-made. The Japanese made rather crude reproductions of only the basic items like the teapot, sugar and creamer. The Germans produced a wildly inventive range of these porcelain wares from 1908 through 1932. If I had to pick my top three segments of the vintage market, this segment would be amongst them. SGV for the handled cup is $125. SGV for the saucer is $175. The saucer was also produced with an orange and burnt orange finish.
07/19 Update: This super combo sold for $344.
