Interesting. Perhaps at some point he got fed up with people heisting his stuff and reselling to others. Ñone of the commercials I purchased from him had any watermarks. But as I stated above that was back in the 80's maybe earlier. It's hard to remember now.
Ira Gallen TVDays. No one on Planet Earth has more high quality vintage commercials than he does! I know because I bought hundreds directly from him back in the 80's. Good guy too!
