An exhibition about Douglas Adams is not a common event. Last time I saw one was the Hitchcon in 2009. So if you're in UK when the exhibition is open (this october) you won't want to miss that.
"By kind permission of the family of the late Douglas Adams this unique exhibition is a unique first public display of some personal memorabilia that documents the birth of The Hitchhikers Guide to the Galaxy at his home in Stalbridge, together with items from his passions for technology and conservation.
The Oliver Holt Gallery
October 6th, 11th, 12th, 13th, 16th and 17th from 12.00 – 18.00
