this looks like trash, I have IP autographs from andy and martin which have changed very little over the years and there nothing like these,looks like it's been signed by the same hand....
Could you post them please? To my eye, this LP's signatures seems similar to the one by another user here in this forum. Maybe I'm wrong. Some other DM's experts?
He sells a lot of Depeche Mode items. This one does not look like others I used to own and have seen and does look like one hand signed all 4 signatures. For me it looks off and if it seems too good to be true then it usually is.
