I have an Alice In Chains autograph from 1993 lollapalooza tour. It is signed my Mike Inez, Layne staley, jerry Cantrell, and sean Kinney. My dad toured with bands as a lighting technition from 1964-1998 and I have many autographs but I'm interested in finding out the value of this particular one. I didn't know where to start, so here I am looking for advice. I haven't had it authenticated yet, but that won't be a problem. I also have VIP passes from that tour and possibly my dads tour book the crew got. I've looked around and I've seen such a wide variety of values. It is personalized to me, Melissa. Just looking for advice and knowledge. Sincerely first time blogger.
