Two Peter Marxer Briefmarken-Auktionen (stamp auction) catalogs from Vaduz, Fürstentum Liechtenstein: the 40. Auktion of 17–18 October 1985 and the 41. Auktion of 17–18 April 1986, both held at the Hotel Schlössle in Vaduz. German-language softcover catalogs with color covers illustrating Liechtenstein, Swiss and Austrian stamps and covers, including a 1931 Zeppelin flight cover on the back of the 1986 issue. Used, in good condition with light cover rubbing and edge wear and some toning to the inside pages.

The lot sessions are heavy on Liechtenstein, including Liechtenstein airmail and Zeppelin covers, followed by Switzerland, Germany, Austria (including Zeppelin and catapult mail), Europe and overseas. Each catalog opens with the auction schedule by lot number and a map to the auction venue.

A useful philatelic reference for Liechtenstein and Alpine-region collectors, and for anyone researching provenance, lot descriptions and the 1980s European auction market. Both catalogs are included.
