This was, whether for the UK or US markets, I've no idea, a set of episode previews and teasers for "The Prisoner", probably issued when the show was initially released in the UK in '67, and in the US in '68.
I personally suspect that this set of adverts is for the UK market(even in spite of the announcer's American accent), because of the use of the word "channel" rather than "station", as most American tv show adverts would have used.
But, I could be wrong on that score.
All speculation aside, these teasers should help give something of an idea of what the series was like, even if they don't give the whole picture.
Be seeing you.
