Blakeman & Henderson were active in the period of the 1890s to early 1900s and appear to have imported Limoges porcelains into the USA. They commissioned the decoration, which was always of very high quality.
Blakeman & Henderson Marks and Limoges Boxes
Mark #B45a: Decoration mark in red, green or gray, 1890s
Mark #B45b: Seen with #B45a and possibly a Blake and Henderson mark - but why two marks?
Mark #B45c: Green decoration mark 1890s
We do not known if Blakeman & Henderson imported any Limoges boxes.
