Signed aerial photograph of the Hall
Photograph
This aerial photograph was taken by Bill Graham, former employee of TIRL. He learned to fly planes in order to serve in the RAF. He joined Cambridge Flying Club when he moved down from Scotland to work at TIRL. One day he took a camera up with him, with one hand he flew the plane, with the other he took this photograph.
The image was printed as a leaving present for an outgoing Director of TIRL, here you can see signatures by some of the senior colleagues at the bottom of the image.
