Cartoon Network.com posted these pencils for other, earlier Tom & Jerry opening title cards. A version of the one on the right can be seen at the begining of THE NIGHT BEFORE CHRISTMAS (1941), minus those rings in the center. Were these titles painted and used at the begining of the early forties Tom & Jerry. No film footage has been found as of yet - but it proves that what we see today are not the original opening titles. The only known footage of the original titles is "Tom and Jerry In The Hollywood Bowl"
