A signed letter from the author of 2001

A 1975 letter from Arthur C Clarke to a fan. Clarke uses a preprinted letter which he has signed in biro. The printed text explains the reason that he cannot respond personally to 'several thousand items of mail a year'. Clarke has written 'Dear Mr Wade' at the top of the letter. At the foot of the letter Clarke has signed himself 'all good wishes Arthur C Clarke, 25 Nov 75'. Presumably in response to a request for a photograph the author has highlighted in pen the printed paragraph referring to Clarke's reluctance to send photographs. The letter has been folded twice.
