Extremely rare Royal Flying Corps poster from WW1. These were used to teach novice pilots during the First World War and were issued by the Air Ministry. The poster is in fairly good condition given its age, there is wear along the edges as shown.
The poster has been taped to the frame for quite some time and I would suggest having a professional remove it if you do want to separate it from the frame. Happy to provide more pics or answer any questions I can.
