The links are from Facebook, but I see nothing on Mark's FB page.
Note that is says PS # 5441, whereas the latest PSFriday posts have PS # 6359 and other nearby (and even higher) numbers featured, for example. So the above guitar is about a year ahead in the production line, which means it was probably out the door a long time ago...
So Dusty, where'd you find these shots?!
Looks interesting...
