What if Warner Bros. got the notion to restore the credits to the Merrie Melodies cartoons that have no original titles available? Judging by the Golden Collection DVDs, they've found plenty of the original titles, but some are still missing. Would it be too much to ask if they created new title cards to give credit to the people known to have been credited? They did something like that for the music cue for "Bashful Buzzard" on the latest collection. Here's an idea, using an animation drawing of Sniffles, Photoshop, and a couple crappy Youtube files, of how they might go about recreating titles for "Bedtime for Sniffles".
The bullseye/tunnel titles are from "Confederate Honey", made the same year, 1940. The title card is my own creation, using an animation drawing of Sniffles.
