The previous convention,
Nolacon, is a plot point in
The Case of the Little Green Men, the first novel by
Mack Reynolds, which is set in part at "AnnCon", a fictional version of the 10th World Science Fiction Convention held in 1952. The real 10th Worldcon, held in
Chicago, had no actual name like "AnnCon", being simply called, in its own publications, "the 10th Annual World Science Fiction Convention" (and once as "the 10th Annual Science Fiction Convention," likely a dropped-word
linotype operator's typo). Before and during the convention, its attendees often referred to it as "Chicon II," an unofficial
nickname that stuck to this Chicago Worldcon in the decades that followed. == See also ==
