OrlandoCon
OrlandoCon, also known as O'Con, was a long-running comic book fan convention which was held annually between 1974 and 1994 in Orlando, Florida. The first comic book convention held in the Orlando area, OrlandoCon billed itself as a "Central Florida comic art convention and early TV/film festival." Captain Marvel-creator C. C. Beck was a regular guest of the show; as were many other Golden Age of Comic Books creators who lived in the Orlando area.
The founders of OrlandoCon were regional chairman of the National Cartoonists Society Jim Ivey, and local enthusiasts Charlie Roberts, Richard Kravitz, Rob Word, and Neil Austin. Most OrlandoCons took place over a September weekend.
