In the first issue of Howard Chaykin's miniseries The Shadow: Midnight in Moscow, published by Dynamite and set in the early '50s, the Shadow attends a dinner party with several other adventurers. Though not named, the host is Nero Wolfe, and the other guests are Tarzan, Doc Savage, and Bulldog Drummond. Farmer identified all of those present as members of the Wold Newton Family. But the really cool part of this scene? The picture hanging on the wall in the background is a photograph of the real monument to the Wold Newton meteor. I for one love this, and will definitely take note of it when I write this series up for the books.
