I need help in identifying the English name of 4 Japanese SciFic TV series



WHAT is the English name of these 4 series back in the 70's?

and while I'm at it, how much are each one of these card worth? and what do you call it? a photo, a post card? what's the name of it?
can you click that link? when I click it, that JPG loads up very fast. There are only 4 pictures in that jpg.

does anyone else know how much these card is worth today?
