Steve Stanchfield might know the answer to this, but I swore 16 years ago, I was in Atlanta, and watched an episode of Matinee at the Bijou, with Boy Meets Dog with the Universal Pictures 1940s logo on it.  I think I may have seen the Ipana plugs intact on the print as well.   Now, knowing that Matinee does "restore" some UM&M. shorts with Paramount logos, I'm starting to think they may have used a Castle print, and put the Universal logo on there.   Did they do theatrical prints of Boy Meets Dog, or was it a "restoration" by Matinee at the Bijou?
