The OPC factory in London, Ontario packaged branded baseball cards for the kids north of the border starting in 1966, although Topps had been producing cards for Canadian distribution for many years prior. This 1967 OPC baseball wax pack, authenticated and graded PSA 6, has the same wrapper and card design as Topps cards from the same year, with print designating them as the OPC version. Tough and beautiful pack, with numerous stars possible inside.
