Are PCGS TrueView Images in Public Domain

I've seen TrueView images published in books and magazines plenty of times. Typically, if it's in good faith, this is free advertising for PCGS and their photo services which are actually decent, and have the benefit of being taken without the plastic holder in the way. Use common sense, just contact them for permission before any potentially-commercial use. Typically if you're a member, and are publishing and implicitly advertising to other prospective members, that's a no-brainer for them.

I’d expect that fair use rules apply and bear quite a bit more weight for anyone that uses a TrueView. It’s all based on how it’s used IMO.
