I've got a chance to buy this autographed 8x10. Guy says it's authenticated by Star Authentics (not Pro Star but just Star). He says he's also gotten it verified by a third-party handwriting expert for what it's worth.
I don't deal in autographs of these types of players (mainly deal in 70s-90s players), but it's a decent price he's offering it at (and one within my range). So I'm highly interested if it's authentic. Note, he's not giving it away, and the price isn't a red flag. But he's got it at a decent price that at this time I can actually afford.
Here's what the picture and autographs look like...
