I love this book. Reading the postcards is fascinating. I love the little illustrations John and Paul include on their postcards. I don't know, but because the postcards are written to a friend, I feel like you get a little glimpse into their private world and personalities. John telling him to record something like Heart of Glass, Paul drawing a rebus puzzle instead of writing a note, and George sending him a postcard of some naked man! And there's commentary on every page as far as I remember. Don't know what else he could have written. The postcards speak for themselves. I mean, these are private items we're getting to see and read. Anyway, it's a nice change from all the Beatle bios and Beatles day by day and so on. I got it as a gift though, so I didn't think of price. Although, I probably would have bought it anyway.
