MyFINBEC is an collaborative art project that gathers street artists from Europe every year. The artists each paint on wooden wine cases stacked on top of each other, the paintings will be used as the labels as well as the package designs.
Below is the video of the project in 2012 showing the stages of the event. It is pretty fascinating and inspiring to see the various possibilities created by the artists making use of sprays and other tools (brushes, threads etc.).
