"Preservation of ASL" I think-- is the title of the video with Veditz on it.
Your best try is to check it out from an ASL language lab or try CMP (new address is CMP) and see if they do have it in their catalog. It is for Deaf people who need to watch educational videos-- they do have some videos in ASL with captions.
Hey, I recalled I recently received some info about the George Veditz works and that it would be shown in Boston. If I still have that info, I will post here.
