Fanderson 91 "Supercelebration" marked 10 years of Fanderson and 30 years since Supercar. The hotel was the Hilton in Leeds- which originally had been named the Dragonara Hotel, and was the location of the first convention, Fanderson 81.
The convention was held on 26-27 October 1991. The convention book was 24 pages, with an orange background cover, but black and white photos throughout.
There was a history of Fanderson by chairman Chris Bentley, a set of series guides and a list of episodes.
The programme guide. The overnight screening was a convention first- made more challenging by clocks change adding an extra hour. While some episodes were now on commercial videotape, and some fans had home tape recordings of recent repeats, even the most dedicated fans who attended these conventions would not have seen some episodes for decades, or perhaps ever.
