Early urban spam

I always thought that ambient advertising and urban spam were relativly recent ideas.

By recent I mean the last 20 years.

Turns out advertising has been invading public spaces for a lot longer than I realised.

Back in 1930 a Barcelona wine merchant used a rolling drum and stencil to advertise his wares on the pavement.

Unlike today's interuptive advertisers he didn't use paint.

He used water!

Which meant that after a while his messaging disappeared.

Environmentally sensitive advertising. In the 1930s.

Who'd have thought?
