A copy of a sketch which was published in the "Illustrated London News" on 1st.May 1943.

The caption read "One of the most important and least known of our Defence Services - Watchers of the Skies; The Eyries of the Royal Observer Corps".


Typical of the many country posts manned by the Royal Observer Corps : with telescope and glasses, a wide expanse of sky can be kept under constant survey. This post was made by its members, and consists of a large section of concrete conduit.
