As we've been discussing obscure 70's opc variations, I'll post just in case anyone else is interested...
1976-77 OPC Gary Simmons #176 can be found with either the "Team transfered to Colorodo" or with a smudged out version. I have no idea which is scarcer. Looks like the person who corrected the error did it at 4:55 on a Friday afternoon.
On June 14, 1978, the league granted approval for the Barons to merge with another financially troubled team, the Minnesota North Stars. The merged franchise would retain the Minnesota North Stars name, but assume the Barons' old place in the Adams Division. The Barons remain the last franchise in the four major North American sports leagues to cease operations, and as a result the NHL fielded only 17 teams during the 1978–79 season.
