Did a deal with Nick and he was awesome to work with. He is pleasant and has a passion for HOF players. My framed and matted Ken Griffey Jr signed picture arrived packed to perfection. If you are looking for quality memorabilia this is the place to go.

I have dealt with Nik and Game 7 Authentics multiple times and I have never been disappointed. I have always been impressed with his inventory of autographed baseballs and other memorabilia and when I am looking for something to add to my own personal collection I usually check to see what he has for sale first. Great customer service, fast shipping, awesome merchandise...
