I found this image yesterday (on the PulpFest website) and it felt strange to find so many of my teenage heroes gathered in a single place.

Otto Binder, Manly Wade Wellman, Julius Schwartz,(front row, crouching).
Jack Williamson, L. Sprague de Camp, Dr. John Clark, Frank Belknap Long, Mort Weisinger, Edmond Hamilton, and Otis Adelbert Kline (back row, standing).

Because there was a time when giants walked this land.
