An original preliminary background from the Don Bluth Studios animated film "Secret of NIMH" (1982). Featuring a beautiful rendering of what appears to be tar on a branch, the hand-painted background was created at the studio and used during the animation process. Don Bluth was notorious for his attention to detail and would often change the layout, look, or color palette in a scene after seeing dailies. A similar but slightly different background appears in the final version of the film. Measuring 10.5"x13.5" overall, with the image area itself measuring 10"x13", the preliminary background is in fine condition with pin holes along the top edge and minimal edge wear from studio handling and use.
