A Careless talk poster, illustrated with civilian and armed forces headgear, with the slogan ‘The more information you keep under your hat' (trilby hat) and the caption ‘the safer he'll be under his' (steel helmet). As with many Careless talk posters, the images focus on the head area, indicating whatever knowledge was contained in the head, it should be kept there.
One of the funniest parties I ever went to was an Old Lady Party. We all shopped our local Salvation Army for vintage hats and orthopedic shoes and what a fun mix of outfits we created! Then we went out later and got asked to dance a lot!
