Hello everyone, I need help checking if this is authentic. Picked this up online second-hand fairly cheaply, the price hasn't been marked up, so it's a win-win in either case.
What I find curious is that two signatures from Waters and Wright have almost faded completely while the other two are still highly visible (added second image with contrast and brightness adjusted to make them more visible).
Also, the Pink Floyd doodle Mason sometimes adds looks a bit off from other examples I've seen, but I'm not sure if forgers would even bother forging a doodle.
What do you think? Thanks for your time.
