Peter Luhn is one of the printer/publishers researched in detail at www.tpa-project.info. The star logo was used from 1897 and "PELUBA" for the last few years from 1924. A general art printer, cards date from probably about 1905 onwards and are not topographical. Many, maybe most, were exported.
Here is some information about the artist of both the example cards Sophie Sperlich.
