This is offered by a major auction company. What do you think? It looks pretty good to me overall but I am always very cautious. It almost looks too good for being 40+ years old on a large paper photo.
The other thing concerning me is it does not come with any third party authentication while many of the other items do. I have mixed feelings about TPAs but a TPA blessing does add value. At a minimum, they will often have a letter showing provenance.
