Battle of Britain: A&BC Card No. 1

Single original A&BC chewing gum card from 1966 film Battle of Britain.
The card has a slight mark down the front (look in the photo at the word "retreat" in the 5 words of text at the top of the card and hopefully you can see it) from an elastic band. Otherwise it is in excellent condition, corners still sharp, no other marks, creases, stains, etc.
