Max MUNK, Vienna and Paris
This publisher's cards are artists illustrations, not photographic or topographical. The publishers mark is on the address side. The cards were clearly very popular in France as indicated by the use of the name Vienne and the presence of a Paris office, at 16 Cité Trévise . The cards with marque M M VIENNE sometimes also carry the name M MUNK. Other cards bear the legend M MUNK WIEN. The card posted in Budapest with just the logo M.M. is also presumably a Munk card - there are Paul Ebner cards bearing just MM as a logo as well as ones with MUNK logos. According to metropostcard.com (now gone) the cards were all printed in Austria.

I found the following article titled Max Munk (fl. 1900-1917) on the internet. "An important publisher of artist-signed greeting cards covering a wide range of subjects and styles. They are best known for their holiday cards and images of women. Their cards are made in Austria, originally using chromolithographs, which were later replaced by the three-color process. These cards are usually Only labeled MM Vienne. They also published a few scattered postcards for Detroit Publishing Company."

Could you remove your email details, please?

I see other of his cards that have a signature. This one does not appear to have a signature. It might be the publisher himself drew this kitsch.
