Hi all! I bought this tall black vase with purple and yellow flowers, ceramic, at an auction. It has a bottom stamps that appears to read "403 30 Germany" on the bottom. I read that these types of dual bottom stamps from Germany are usually first the style number, then the height in centimeters, and this seems to be correct as I measured it at 13 3/8" H. It's 5.5" W at the mouth and the widest part measures about 26" all the way around (2'2"). It's 4.6 lbs. I have been searching and searching to identify the maker on this piece, and/or to date it, but have had no luck yet. Anyone have any ideas on it? Thanks & hope you're all having a great, sunny week!
