The original 1948 version of "Mouse Cleaning", uncut. This includes the "shufflin' Tom" scenes at the end (which were replaced by Chuck Jones' unit at MGM in the early '60s). This version is no longer available on DVD or BluRay in the US.
This is a very good avi rip, source unknown. It is in Academy Standard AR of 1480x1080. This will complete the T&J Collection recently uploaded - H&Bs total output of T&J cartoons from 1940 to 1948 was 38.
