Wow, that was much faster than expected!
It is indeed a Möve tricycle built between 1903 and 1906 by Walther & Co (later Walter & Co) from Mühlhausen in Thuringia. They built three-wheeled rickshaws and "Sesselräder" (tricycles with a cofortable front chair) for the Asian market.
The picture comes from a book about cars, motorbikes and motor sport in Mühlhausen. I happened to buy the last copy of this book at the publisher's shop in Mühlhausen this summer.
