Broadleaf 350 back. Extraordinarily rare example of William O'Neil's T206 card with the Broadleaf 350 reverse. Ranked by T206Resource as the eighth most scarce of all T206 backs (including the Brown Old Mill and Ty Cobb back), a search of the SGC and PSA population reports yield just one example with the Broadleaf 350 reverse - this one. Clearly, at some point during the history of each grading company, back advertisements were not considered during the data entry process - so it is entirely possible that somewhere exists another specimen that is not easily found in the pop reports. However, searching each company's census reveals the certainty that this is a truly rare specimen, a card with one of the lowest populations of Broadleaf advertising reverses to exist. The card itself presents well, though some soiling and surface abrasions have marked up the reverse. It is, of course, the rarity that makes this card special, as opposed to the condition.
