This wooden plaque was commissioned by the parents of a pilot killed during the Battle of Britain in 1940.
They asked Robert 'Mouseman' Thompson to make a plaque in 1942 in honour of the 'Tiger' Squadron of the RAF. He took pride in his commission and the detail includes his trademark mouse on the top.
