Here's an interesting item that caught my eye on eBay recently (and you can Buy It Now for only $1,799.00). A script page from 1988's Who Framed Roger Rabbit, signed and written on by Mel Blanc, of a scene that wasn't in the final film. This scene is of the funeral of murdered Toon Town founder Marvin Acme, featuring Felix the Cat, Elmer Fudd and Yosemite Sam as pallbearers and Foghorn Leghorn delivering the eulogy. There are also appearances by Bugs Bunny, Humphrey Bogart, Clark Gable, and a certain mouse.
If you look closely, you can see Foghorn in this concept drawing of the scene (buried among the extras on the DVD).
