Hi there, signed by Malcom twice, Angus, and Cliff. Bon has also signed. It is large and hard to see (faint) on photo due to thin blue ink but seems consistent with other pieces I have seen.
An US printing, see lower right corner of the innersleeve.
The idiot who faked these autographs didn't even know that the album wasn't released in the US until 1981, a year after Bon's death. But even without that those are bad, bad fakes.
