Maybe I should ask which picture you are speaking of first but something tells me that it is doctor who related based on the last posts of this topic. :-/
Well, obviously the expression "Time And Relative Dimensions In Space" is the answer. I watched the Doctor and his grandaughter and her two teachers as they went to see Marco Polo and others right from the very first transmission on BBC on a Saturday evening.
In those early days, it was intended to be educational, as much as entertaining. So we learnt how to extract drinking water from a desert environment and other useful topics. We really needed that information in South London!n
