Ars Gratia Artis

Sir,—There has been something peculiar hanging on the northern wall of the men's common room for some time now, and I have been unable to find out what it is. Suggestions I have heard include a scene from a Silly Symphony, a liberty loan poster, the Professorial Board, a rare action shot of a civil service department at work, or a painting of some merit and worth. Please be a light to lighten the darkness.

[The last suggestion you name was the nearest to correct. Wolfie Rosenberg, will in all likelihood be prepared to give the curious an authoritative exposition, on the topic if approached with the deference which is his due.
