Look out! Keep your eye on the binlins

Ministry of Aircraft Production Second World War poster. It depicts a mythical pig-like creature called a 'binlin' who sabotages production and efficiency in warehouses - the binlin is inconsiderate and causes trouble by messing up the order of paper records, metal parts, and by littering and hoarding. The majority of the poster is a poem about the binlins printed in black on a red background. The binlins appear as a small cartoon characters several times amongst the text. The title is printed in black above and below the text.
