My late husband was a disc jocky for 40+ years and was a collector of rock n roll memorabilia. Autographs, guitars, and in particular a pair of vintage levis signed over many years of back stage meet n greets. It all started when he was backstage with nothing to sign on and said "here, just sign my jeans" and the rest is history. I'm interested in the value of these jeans in hopes that if sold, the money can help support my kids and I. I can help with authenticating these with photos, backstage passes and concert tickets. if anyone knows a top notch appraiser any suggestions is appreciated.
