These are the original lead Marvel character designer concept art sketches from the HULK VS. THOR animated film (2009). These are the very first sketches of these characters done when they first started working on the film. Many are titled and have the Marvel archive serial number stamped on to the sketch. It doesn't get any better than this. Frank pair/Jeff matsuda supervised and even helped create these drawings.. these are the first art pieces from this film put up for sale. Movie: Hulk vs. Thor Character: Sif (concept art sheet, shading sheet, and original model sheet) (hand drawn) two 17x11's and one 9x11
