Plan B was a one day convention held on 25 May 1991 at the Conway Hall, Holborn, London. Later that year, Fanderson held a two-day convention, Fanderson 91. The Conway Hall was the location for Fanderson 86, on 24 May 1986, and Uforia, on 18 June 1988.
This one day event had a short black and white booklet, with a "series file", listing each of the series and Fanderson's contributions, and the programme. Most conventions have problems keeping to schedule, but when the guests disappeared off to a restaurant for lengthy lunch, Plan B's afternoon guest talks were thrown into chaos.
Most conventions had one or more "progress reports", short 4-8 page reports listing travel details, invited guests, and asking for art displays and costume competitors.
