Posting this monster for the Celtics - they need all the luck they can get! This was the pre-SGC company, called SBC. They had the same grading scale that was adopted by SGC. This has some of the best colors and surface of any Russell rookie I’ve ever seen. Outside of the clear centering issues that many of the 1957 Topps set had, this one is super nice. I’d only trade it for a lower grade Russell rookie auto if someone has one to move.
