(Apocryphal?) anecdote about Fahrenheit 451

From one of my favorite blogs about books, Bookride, a "tall tale from the trade":
200806271356.jpg A similar tale is set in 1965 in a provincial bookshop where trade is slow. The dealer has a sale of the books upstairs, lesser books but useful stock--even after severe reductions there are 10,000 books left. Rather than haul them down to the dump he decides to give the whole lot to the young girl who comes in on afternoons when he is out doing house calls, fishing, watching cricket etc., She graciously accepts them and says she will arrange to have them out as soon as possible. He sets off to a local auction and on his return is greatly surprised to find all the books have gone. The girl explains that a guy came in from a movie company needing 10000 books - for the book burning scenes in Fahrenheit 451 that they were filming nearby. She only charged £1 per book.
