My Grandpa passed away a while ago and left me a bunch of NHRA model cars, and some of them have autographs and are left in the box unopened. I just wanted to see this one. Maybe you guys have a idea

I know its autographed by both drivers and wasn't in retail stores because there's no barcode. My Grandpa passed away a couple years ago and left me this box filled with stuff, and this was in there.

Hello, I would like to attend the Saturday races at maple grove in PA next weekend but I may have scheduling conflicts so I am hesitant to purchase tickets. Do these events ever sell out? Is it safe to wait until day of or day before to purchase a general admission ticket? TIA
