I have seen the smiley faces and people of Berlin-based Street Artist, Mein Lieber Prost (often shortened to Prost) on the streets of Berlin since I first visited the city in 2009.  His simple but effective drawings and occasional advertising takeover antics always bring to mind the phrase ‘Smile and the world smiles with you…’.

A number of his pieces appeared during a spree with ALIAS (see my post ALIAS: Busy in Berlin) and TONA (see my post about him here).
