Recherche dans la collection - [Etendue du pays qui serait couvert par un système national de radio diffusion]. [cartographic material]

A map very similar to this was published in 1931 in a pamphlet sponsored by the Canadian Radio League. Although the pamphlet map was greatly reduced in size, the concentric rings added in manuscript on this map are identical to those on the printed map. These rings represent the reception contours of a proposed national radio broadcasting network. It is not known if this map was drawn prior to or after the publication of the pamphlet. The manscript features are drawn on a Department of the Interior map of Canada entitled "Dominion of Canada".
This map is from the Col. Steel Papers, M.G. 30, A17, vol. 29, file 160. The N.M.C. holds a photocopy of the map published in the French translation of the pamphlet: F/1100/[1931]. The P.A.C. Library holds the English version containing the map under: HE 8699 C2C272 1931. For a full map note see F/1100/[1931] (set of 3).
