Stokes is holding the 1970 Dover Occult edition of L. Sprague de Camp‘s Lost Continents. Dark They Were and Golden-Eyed, the place that inspired Sherry Gottlieb to open A Change of Hobbit, was also London’s first comic shop, predating Forbidden Planet by more than 10 years. It closed in or about 1981.
And here’s a store bag from 1978. The artist is James Cawthorn, an illustrator primarily associated with Michael Moorcock who also co-wrote (with Moorcock) one of my favorite movies, 1975’s The Land That Time Forgot.
