One Russian online company has started its ad campaign by putting those paper ads on the telegraph poles and bus stops in major Russian cities. The ads contained the offer for some not very common goods, like "Large Hadron Collider for sale, cheap, customer pick up from 30 feet underground in
Europe" or other stuff like that. They put futuristic looking flying cars, moon luxury properties etc on those ads and intrigued people. I don't know if they succeeded in gaining enough attention for their services in such a manner, but those are pieces of their ads.
