It's an original which my uncle bought when it first came out - says 1973 on the inside cover. I'm not going to get rid of it but just wanted to know the value.
I was only aware of PF when they released Another Brick in the Wall. This was when I was a kid. The rest of the albums before that, I started listening to a lot later on in my 20s. My fave is Great Gig in the Sky.
