The most expensive, a watercolour of Neuschwanstein Castle in Bavaria, is expected to fetch around €45,000 (£33,000).
The watercolours and drawings date from 1904 to 1922 are on offer, and several are signed “A. Hitler”.

Hitler was a failed artist before he turned to politics, and his paintings still regularly come up for sale.
Last year a Hitler watercolour of the Munich town hall sold for €130,000 (£95,000) at the same auction house, to an unnamed buyer from the Middle East.

The trade in Hitler’s artworks is controversial, and buyers often choose to remain anonymous.
In March a Los Angeles auction-house withdrew a still-life watercolour painted by the future dictator at the last minute.
Selling the paintings is legal in Germany so long as they do not contain swastikas or other Nazi symbols.
The Weidler auction house in Nuremberg has become known for has said any complaints over Hitler works offered at should be addressed to the sellers.

In his youth Hitler wanted to become a professional artist, but he was twice rejected by the Vienna academy of art after he failed the entrance exam.
He persisted and produced hundreds of works, selling paintings of houses and postcards to try to make a living, but was not successful.
The 14 works on offer at auction include watercolours of buildings in Vienna and Prague, a still life of carnations and a drawing of a nude.
The watercolour of Neuschwanstein Castle is believed to have been painted as an 80th birthday present for Otto von Steinbeis, a German industrialist.

For anyone interested in the dubious attractions of hanging a genuine Hitler on the wall, the cheapest drawings are listed at €1,000 (£725) each.
