High Patrol illustrates the famous WW1 fighter the Sopwith Camels of 209 Squadron RFC in 1918. The print is personally signed by the designer of the Sopwith Camel and one of the greatest pioneers in aviation history Sir Tommy Sopwith. This is a very rare Artist Proof that is also signed by Balfour Inchrye and Aubrey Elwood both Sopwith Camel aces. 

There are very few signed WWI aviation prints certainly none with three signatures of two Sopwith Camel Aces and the designer of the Sopwith Camel.
