It’s fine with me. As long as you’re not making a profit from the hard copies, you can do what you like. The one thing you should perhaps be aware of, if you’re planning to print it, is that all of the nice photo images of stuff (the pen on the opening page, the picture of Mr. Potato Head, etc.) are illegal. That fact is, I believe, mentioned in the Foreword. I have never sought rights to those images, and wouldn’t know where to begin. I went to some trouble to get the layout to wrap around the images in a nice way, so if you delete the images you may have some fun reformatting the layout. Or just take your chances and print the silly thing as is – no one will ever know.
