There are still a handful of artists out there keeping the art of hand painted, large scale advertisements alive. Only a few decades ago, all building and billboard size advertisements were painted this way. Now, most are printed on vinyl pieces and glued piece-meal to the sides of buildings or billboards in a most un-artistic and impersonal way.
Up There, by Malcolm Murray, chronicles a group of artists working on a Stella Artois campaign in NYC. The campaign portrays the Belgian Pouring Ritual in a series of nine 20 x 50 ft paintings on the side of a SoHo building. All nine paintings were made in 21 days and the end results are captured beautifully at the end of this short documentary.
