This ad seems to be product of another attempt to produce innovative ads. The idea is of course brilliant but seems to be effective only in less populated area. Forgotten wallets predictably take on the streets of Sao Paulo to advertise.

Yet again, this is difficult to conclude whether the wallet is just carrying message of the product or it is a complete wallet that can be used by the passer by who has found it. If the latter part is true, it is going to be effective.
