() Here we have an amazing hard to find hand-painted screen used panoramic animation cell background from the Depatie  Freleng animation studio .This piece is roughly

35 in Long  !!!!!!!! . This background is from The Pink Panther series but will work with most cartoons out there ( Hanna-Barbera, Looney tunes,  and so on). There is a light crack on the right hand side. Not very noticeable. Do it being so long you could just cut that piece off or display it as is. It will still look fine
