Five watercolours attributed to Adolf Hitler from his early days as a struggling artist have failed to sell at auction in the southern German city of Nuremberg, possibly over fears they could be fakes.
The Nuremberger Nachrichten newspaper reports that no bids were received on the paintings, which had starting prices of between 19,000 euros ($A30,385) and 45,000 euros ($A71,965).
Three days before Saturday's auction, prosecutors seized 63 other paintings attributed to Hitler from the auction house to investigate allegations they were fakes.
It followed prosecutors' seizure of three Hitler watercolours in Berlin last month after a complaint questioning their authenticity.
As a young man, Hitler unsuccessfully struggled to succeed as an artist in Vienna before World War I.
