Customs officials in Germany have a warning for holidaymakers keen to bring home souvenirs and other kitsch: Coffee mugs with Hitler's portrait, swastikas and other Nazi-related symbols are strictly prohibited.
A 39-year-old man was caught with 13 such dubious mugs in his luggage at Dusseldorf airport, and a criminal case has been launched against him.
The cups will be destroyed after the investigation.
It was likely that the man was not a right-wing extremist. He was merely amused by the mugs. The use of such anti-constitutional symbols, including their importation, is punishable with a fine or up to three years in prison.
