The Avengers Screencaps 25-Mandrake(1964)

I wonder what colour Cathys hat is ?I imagine its red certainly an iconic look  for the early sixties , I remember seeing a pic of Astrid Kirchher the Beatles photographer dressed much in the same way , really a stunning look.
Here's a short edited clip , but you'll   also find the whole episode up on Youtube.. this is the episode where Honor knocked out the guy she was fighting , he was unconscious for several minutes ,which presented a few problems as show was shot live  he was a professional wrestler , just goes to show what a tough chick Mrs Blackman is  (I wonder if Honor still knows all those Judo moves?)
