The Secret Service (1969), created by Gerry and Sylvia Anderson, was the last series in Supermarionation. I saw it on Canadian tv when I was a child. This is the kind of show I remember (a little), but nobody else around me does. Two things made a lasting impression on me: the opening theme and a miniature spy traveling in a special briefcase. A good page about this series here. Thanks, Gerry Anderson, for your imagination! Secret Service, UFO and specially Space 1999 were a part of my childhood.
