Gebrüder Metz, Tübingen and Basel

The brothers were Heinrich and Gustav. There are many references on the web (in German) to this art publishing company, which became a major producer of postcards. One in English is at second.wiki/wiki/gebrc3bcder_metz. The firm lasted from 1828 to 1988. Many of their cards are based on detailed photographic records of places and buildings. 270,000 glass negatives still exist. Cards usually (always?) name the company. The logo in a shield appears from the 1930s.

A branch in Basle was opened in 1897, run by Gustav. By 1907 this was split off and cards become G Metz Basel rather than Gebr. Metz. Basel. There are also some cards marked H.Metz, Tubingen, including ones of Basel.
