If I'm not mistaken, those holograms only designate that the photo itself is official NBA licensed merchandise, as opposed to certifying the signatures.
Hundreds of scammers on Ebay use the "MLB Licensed Photo" statement to lead you to believe that the autograph is part of the "package."
A sort of "insurance policy" would be to submit an image or the entire Ebay listing link to PSA/DNA for their "fast opinion". For 10 dollars they'll respond with their E-opinion to you. If you get a "likely genuine" response, it's an indication that the item will have a better chance than not of being authenticated by them if and when submitted. If you get the "not likely genuine", then pass altogether. Now that's if you'd like to have an "official" COA to go with your item, because I would tend to gauge actual authenticity more by forum opinion than by any of the grading services on most key signatures.
