This is the link, it mentions some sort of spray mask testing. Hopefully Frank will chime in shortly
Sorry not been on for a while, I have one of these myself & kevin B bough I think 8 or more from the same guy, Kim Simmons was contacted & his assumption was they are likely authentic spray mask test samples.
No real way to prove it obviously without solid provenance, so they won't grade but my hunch is they are indeed legit or I would not have bought one myself.
