I was 13 years old when I won this from a local radio station, Z104.5 The Edge -- here in Tulsa, OK. The band signed it at our Cain's Ballroom. I've had it for about 20 years. Apparently, this isn't the only one. I've seen a few of these in the same region. I found one on here that was posted back in 2017. I feel like some of these signatures don't exactly match the one that was authenticated on this website. I also don't know if the middle signature belongs to "Pat" or "Nate." There's also only three, which looks common. 

I'd like to be reassured this is real and maybe get an appraisal.
