I guess "answering fan mail" is open to interpretation then. After all, he's shelling out the money for those pre prints. Having those printed isn't cheap. I'm sure he feels they are answering that mail by including those preprints. A lot of times this will happen just to try to save time. Seriously. Several years ago, back when he was playing, I recall reading an article about Dale Murphy, and how he had invested in an autopen to answer fan mail. The thinking was this would be more time efficient and speed up the process of handling the fan mail. When he started running into fans at the ball park who complained about the machine generated signatures, the autpen machine was mothballed. Point is he didn't do it to deceive, but rather to save time.
