Here's wishing you all a very happy holiday season!
I just came across these images from an eBay auction currently in progress: Amsel's detailed pencil sketch for THE BIG SLEEP remake, measuring approximately 13" x 19". The seller is based out of Georgia in the USA, and the work came from the estate of actress Maureen O'Sullivan and her husband, James Cushing.
I've added these to the film gallery. Little trivia: David Edward Byrd posed as Bob Mitchum!
