the 18th
Today is the last posting day for Second Class Post, so in honour of that, not one but two posters.
Interestingly, they are both from 1952. The smiling Christmas trees above are by Hans Unger, while the festive present train below was designed by T Davis.
Two in one year is a bit unusual, but the BMPA catalogue suggests that the Davis poster was designed to go in shop windows rather than post offices. So off you go then,there’s still time.
