Who were Tonwen Ltd. and what role did they play in The Telegoons?
As far as I’ve been able to determine, Tonwen Ltd. (a.k.a. Tonwen Merchandising Ltd.) was an independent company formed by Tony Young (producer and director of The Telegoons, and a company director of Grosvenor Films Ltd.) and Jennifer Wendy Danielli (associate producer of The Telegoons, and a company director of Grosvenor Films Ltd.), to spin off film tie-in merchandise projects from Grosvenor Films. The company name was formed from the first syllables of Tony and Wendy. The only Tonwen Ltd. product that I know of is the children’s story and colouring book, The Telegoons in The Ascent of Mount Everest, drawn by Bill Titcombe. Incidentally, Bill Titcombe also drew the popular Telegoons comic strip in TV Comic.
