The copyright rights in the performance captured in the footage almost certainly belong to MLB, though, unless they managed to time it just right to allow them to expire. As owner of the physical footage, MLB couldn't broadcast it without Rare Sportsfilms' permission, but the opposite is also almost certainly true as well. (And NBC almost certainly has rights in it as well.) (Looking at their webpage, I'm actually shocked to see that they sell DVDs of this stuff. They must have some sort of permission from MLB/NFL/etc.; or at least those parties turning a blind eye, esp. on the stuff from the 60s and 70s whose performance rights have definitely not expired.)
Interesting stuff. It's like the BBC. They junked a TON of stuff from the 60's, assuming it had no commercial value, including a ton of "Doctor Who" episodes. There are other shows that are gone entirely from history. (All "Doctor Who" episodes exist in audio form, in many cases from people recording the audio from the original broadcast, but quite a few episodes are still missing the video.) I just wondered if MLB had it in a vault somewhere and never released it. I love all this old film stuff. I find it fascinating.
I have an uncle that used to play pro baseball back in the day and who is also a collector of rare sports videos. I have no idea if he still has it but he had this video. I remember when I was like 10 years old and he was watching it with a bunch of his friends when he first recieved it. It ran almost like the films from back when with the whole movie projector and everything but no sound. He had a few different clips of rare sport footage but mostly had a lot of Roberto Clemente videos. I have no idea how he got them but I'm going to get on the horn and ask if he still have these gems. I know he didn't collect any of this stuff for the money since he doesn't need it but I would like to preview these videos just to make sure. Classic stuff. Thanks Ufez Jones.
