Super cool series online by Skateboarder Magazine, "Raiders of the Archives." They are short videos looking into the offices and/or archives (literally, shelves, boxes, walls) of great artists and photographers in the professional skateboard world. This post links to my favorite (though they are all great), that being Andy Jenkins, one of my favorite artists, whom I've posted about before. He gives the rare treat of showing some of the conceptual work that happens before a graphic or ad is made, including sketches and renderings from another one of my absolute favorites, Evan Hecox who does amazing graphics for Chocolate Skateboards.
Very inspiring series, and makes you want to dig into the vaults. (And get organized...)
