Everyone who joind got a membership card - wonder how many of those still exist out there? I found a picture of one online here: http://www.radiotheatrenyc.com/HP-LOVECRAFT.html
And the following picture is an ad for the next issue of Weird Tales Magazing featuring a classic story by H.P. Lovecraft, The Shadow Over Innsmouth!
Weird Tales Magazine published from 9 Rockefeller Plaza, New York City. So what was at 9 Rockefeller Plaza? Here's a shot of the building entrance then and now.
I'm a huge fan of Weird Tales Magazine. They produced the finest weird fiction from the greatest stable of writers ever... H.P. Lovecraft, Ray Bradbury, Henry Kuttner, Clark Ashton Smith, Robert Howard - the list goes on and on. Amazing stuff and you can pick up collections of these stories very reasonably on Amazon. Highly recommended, and highly addictive!!
