I would love it if someone would identify what television series these are from. I have pretty decent knowledge of most of the Japanese Tokusatsu shows produced in the 1970s, but this one defies me. All I know about it is that a Japanese co-worker of my mother's back in the early 1980s gave the stills shown below to me knowing that I was a big fan of monster movies. These were from a show that either her husband, or a relative had worked on, I believe as a producer.
The only identifying mark is this stamp which appears on the back of most of them, which I suspect is actually the mark of the printing place that developed them, and not anything to do directly with with production. Others say Boncolorlab Tokyo. One photo (the one of the orange monster kicking the hero) has some handwriting on the bottom as well as seen here.
Anyway, on to the monsters, heroes and fly-headed villains...
If anyone knows what these are from, please let me know. If you know of a way I can watch this tv series, even better. Thanks!
