In Germany, Adolf Hitler's artworks were sold for a total of €391,000, or about $445,642.25, at the much talked-about auction in Nuremberg on Saturday.

There were 14 watercolor paintings and drawings sold by the Weidler auction house to bidders, who are reportedly international investors from France, Brazil, China and the United Arab Emirates.

Some of the German dictator's artworks depicted the famous castle, Neuschwanstein in Bavaria, buildings in Vienna, a foggy view of Prague, a nude female and a bunch of carnation flowers. These artworks were signed by A. Hitler pre-dictatorship, between 1904 to 1922 in Munich and Vienna.

The Neuschwanstein fairytale castle was bought at the highest price of €100,000 ($113964.50), while the carnation flowers were sold for €73,000 ($83194.09).

"These collectors do not specialise in this painter, but have a general interest in high-value art," said auctioner Kathrin Weidler.

Hitler's painting was also sold by the same auction house in November 2014, receiving an amount of €130,000 ($148151.90) for his Munich register office version.

Mullock's auction house in Shropshire has also sold 15 pieces from their Hitler artwork collection in 2009 for £97,672 ($155327.78).

Time reports that there are no laws against the selling of Hitler's artworks in Germany as long as the pieces do not show the Nazi symbol.

Social organizations and media commentators, however, are questioning the morality of these auction houses for selling artworks made by the German dictator, who was famous for ordering brutal mass killings against the Jews during his regime.

The Guardian added that the head of the Weidler auction house, Herbert Weidler promised to donate the bidding proceeds of Hitler's Munich painting to charities and local civic societies in his previous statement during the 2014 auction.

One of the reported recipients, Altstadtfreunde Nürnberg ("Friends of the old city of Nuremberg"), expressed their resistance to the said offer. Karl-Heinz Enderle told reporters that he was surprised to know that the auction house presumed that they will accept their offer.
