Advertising column
（重定向自Morris column）
Advertising columns or morris columns (French:Colonne Morris, German:Litfaßsäule) are cylindrical outdoor sidewalk structures with a characteristic style that are used for advertising and other purposes. They are common in the city of Berlin, Germany, where the first 100 columns were installed in 1855. Advertising columns were invented by the German printer Ernst Litfaß in 1854. Therefore it is known as Litfaßsäule (Litfaß column) in Germany, and can be found all over the country there.
