[Police] andy's plectrums

i am looking to get my hands on some of andy's picks from the early days: ya know the gibson brand - black medium gauged rounded teardrop ones that he stuck extras of underneath his pickguard on the telecaster? still i am trying to determine if andy had his name or some other sort of personal insignia printed on the picks. so if anyone has some of his old picks, do speak up! after all those police tours surely someone grabbed a pick that andy sent flying into the audience?!
