Clifford Harry Knight's birth is registered in December 1929. So perhaps both the posters were done in 1940. On the Help to Convoy The Food he wrote : age 11 years and 7 months, and Clifford Knight, Age 11, War Weapons Week Feb 15th 1940, on the second poster. He had entered for his school at Higham Ferrers.
The second for National Savings and has a label - 12 - affixed so perhaps entry number 12 in the competition to design the posters. (we have no information about the competition or the outcome; if you know, please contact us.)
