I think Richard "Hankster" has solved the mystery. As many of you know, I just returned from driving California-NY-California as my 95 year old mom just got out of the hospital and moved into an assisted living facility. I was, among other things, clearing out my mom's apartment and brought this interesting piece back with me. I've been staring at it for years, or even decades. My wife and I were puzzled, so we thought what better esoteric knowledge base than this group of folks. Y'all came through! (Though I would prefer if it were actually Sword-In-The-Couch ... I'd love to rule over Barco-Lounger Land).
Bill, tgo
