German authorities have seized four wine bottles sporting labels that allegedly praised Adolf Hitler at a restaurant in southern Germany, local police said on Monday.

The Augsburg Police said in a statement it had started proceedings against the restaurant's owner, a 49-year-old German national, for selling bottles labeled as "The Führer's Wine."

The suspect is likely to be charged with the use of symbols representing anti-constitutional organizations, a criminal offense.

The wine bottles' labels featured Adolf Hitler's likeness coupled with slogans such as "Sieg Heil" ("Hail Victory") _ a common phrase heard at Nazi rallies now banned under German law _ and "Ein Volk, Ein Reich, Ein Führer" ("One People, One Empire, One Leader").

There are several brands of wine and beer _ usually manufactured in Italy _ that are marketed using Hitler's face or name.

Although public displays of Nazi symbolism are prohibited in the German criminal code (section 86a), importing "Hitler-wine" into Germany is not illegal.

Police officials in Augsburg, Swabia (a region of southern Bavaria), inspected the restaurant after a reader of local newspaper "Augsburger Allgemeine" wrote a letter claiming he had seen "Führerwein" in bottles displayed on the establishment's bar.
