Wow, I had forgot that Rin Tin Tin is something I can recall from my childhood. I'm not even sure I remember how I know about him, other than hearing the name and seeing random bits of media (maybe even stuff in advertisements or posters). Maybe one of the shows or movies was still played in the 80s when I was a young child, or perhaps the 80's were soon enough after some of the popularity in the 60's that it was still in the public consciousness, and the turnover cycle of pop culture wasn't as aggressively fast.
