That is news to me? It is listed in the TGT as 1972-1973. I would guess you posted a chip that was from a different River Queen although I see nothing in my references that speak of River Queen/Canada. Clearly this matchbook boasts 21 and craps and I assumed the USCCPG listing for River Queen was correct? I've been seriously collecting casino stuff since 1996 and I still feel like a newbie. BTW I did not recieve a reply from you about the Sky Ute/Ute Mnt chips or your interest in the CO club?? Eric
