This is from an art project in Vienna called Delete!, where they covered everything, which could be seen as ads in the Neubaugasse.
Signs in shopping areas should be limited to one sign as an identifier of the store. Logos should be allowed, but size should be limited--small and near the front door. No advertising of products, no window signs screaming "SALE!", etc. No fucking video signs, or animated signs of any type--no flashing lights, or physically animated signs.
We need signs to find the store, that's the purpose to which they should be limited.
