 The first teaser poster was inspired by a fan @-@ art poster by Italian artist Federico <unk> . His artwork was published in May 2011 , a few days after the synopsis and the official title were released to the public . In August 2011 , at Tarantino 's request , the production companies bought the concept artwork from <unk> to use for promotional purposes as well as on the crew passes and clothing for staff during filming .
