There is, in fact, a better way.
On December 5th 1854, Ernst Litfaß, a German publisher and printer, was given permission by the Berlin chief of police to put up his advertising columns. The first advertising columns were put up in that city in 1855. They served as a source of news, advertisements as well as for dispatches from the Franco-Prussian War of 1870-1 onwards.
In 1868, the printer Gabriel Morris erected advertising columns in Paris. Columns serving as urinals and advertising had been in use since 1839, however, the Morris column, used solely for advertising, was a welcome innovation, and quickly got a monopoly in Paris. In 1986, the Morris company was bought by JCDecaux, now a major producer of advertising columns all over Europe.
