"I stumbled across a Led Zeppelin vinyl labeled "Flight of the Zeppelin 1969 at BBC Studios London, England imported from UK Jolly Good Sound". Can bạn tell me thêm about this and its value at all?"

That is a bootleg LP. bạn can tell because the picture is from the 1979 Knebworth Festival show. These tracks have been bootlegged a zillion times and the only official release was the BBC session box set. Depending on the condition it's probably worth $19 - $29.
