For this small, but frankly amazing, piece of information I have a person called AP to thank (he is a frequent commenter and loyal follower of this humble blog). He is also the person who has supplied me with ALL of the screen caps for each of the HK-based episodes, so a very big thank you to AP.
AP has been kind enough to supply me with standard screen caps on an episode-by-episode basis, so I will stick with that format, and also done some rather snazzy merges to create some revealing panoramas of 1965 HK. What makes me smile a bit about this series is that, according to wiki, it was actually banned in the south of the US because it used Cosby as one of the main stars. Many of the scenes we will look at have Bill Cosby running around some fairly remote parts of the NT, and in 1965 someone with black skin would have been an absolute head turner in pretty much all of the New Territories given the significant rural character of the place at the time.
Anyway, a big thanks to AP for sorting this all out for me (and you), I am his conduit and all I am doing is trying to pin down some of the places he has sent to me. So, before we get started with the screencap biz, here is the series' opening titles courtesy of Youtube.
