I'm not quite sure why you would want to cut this signed photo. I would keep it as is and find a suitable cut. I have a Springsteen signed card which Epperson has approved. If you want to see it pm me.
Just sent you a friend request. Once you accept we can message each other.
May be just a coincidence but I noticed you are from SC, there is a Dr. Scott Wein who lives in Raleigh.
Yeah, definitely don't cut it. Signed photos are almost always more desirable than cuts.
I use RR past auctions as a guage for market prices. You may find it helpful for your Springsteen.
