Andy Porter (seated in the front in the 1966 photo at right) writes: Working with Bill Burns, I scanned in many old photos of US and UK fans and professionals going back to the 1930s that Forry Ackerman sent me. I also scanned in many photos I took, primarily from the 1960s (the ones in color). They are all available for viewing in this Flickr set.
Some of the classic names you’ll recognize in the photos include Bjo Trimble; Robert Bloch, Frederik Pohl, Robert Sheckley, Brian Aldiss, and Forry Ackerman in Brazil in the 1960s; Bruce Pelz; Jack Speer from 1938; Willy Ley from 1948; Ted White and Lester Del Rey from 1967; Roger Zelazny and Robert Silverberg from 1967; and Leigh Brackett, Ray Bradbury, and Edmund Hamilton from 1968.
