I think the question of which of Jackie's cards is his true RC is an intriguing question worthy of debate. There's been a ton of research that has taken place by board members discussing the issue and to me it's either the 1947 Bond Bread Robinson portrait (white border) with facsimile auto, which I think most agree was a promo card or the 1947 D302 Bond Bread with cropped corners. There's absolutely no question both of these (along with the white bordered 12-card Jackie set) pre-date both the 1948 Leaf (actually produced in 1949) and the 1949 Bowman, but I don't think a consensus has been reached to date regarding which was Jackie's absolute first card. Pretty amazing considering the player and his impact on modern day sports and civil rights, much less baseball.
