I have seen some postings, less than a year old, on Knopfler's signature. I have tried to search for "clues" but it still is not easy to tell. Would like some feedback on a couple of them I think are real (using RR sales as my "truth tables" for the most part)

One is on a Tshirt (with the rest of the early 1990s travel band from Dire Straits) Clark, Illsley...

Other one on a photo (recent eBay sale)

Is either/both/none genuine?
