Examples of this cold painted bronze dog’s  head stamp box turn up fairly regularly at auction. They generally seem to sell quite well, and why not – they are attractive, well-made boxes. One in a recent auction was described as “Bergmann style”; a description we have not noted before.
“Franz Xavier Bergman (1861-1936) is, arguably, the most famous of the Viennese cold-painted bronze artists …” (millersantiquesguide). The factory closed in 1930 due to the great depression but was later reopened by Robert Bergmann, son of Franz, and operated until his death in 1954 (Wikipedia).  The name is sometimes spelled with one “n”, sometimes two.
An internet search for images of Bergman bronzes will produce hundreds of results which will demonstrate that Bergman-style is a fair description of this box. Now here’s the thing: none of the dog head boxes have been noted as having a Bergman mark and they only seem to have started appearing on the market about five years ago. So, who made them; are they quite modern?
