Not shown here is an equally impressive (but harder to photograph) 3/4" rock below the wire groove on the opposite side. Amazing that it did no damage to the glass. Remarkable overall condition for a 101 - especially one with so much junk! Got this from Jim Peach at the 2004 Mid-Ohio show, but it was previously in Dave (Junkinglass) Watkins' collection. My turn to give it a good home.
