Peter O'Brien
Dossier
Peter O'Brien. On the cardboard side, his vintage presence is anchored to the T206 White Border issue, which is where collectors of the period most commonly encounter him. His T206 White Border appearance places him within the 1909-1911 American Tobacco run, the foundational set of the modern collecting hobby. For collectors, his T206 White Border appearance is the principal tangible record of his playing days, surviving in the same checklist universe that documents the bigger names of his contemporaries. His career sits within the deadball era, the pre-1920 stretch of low-scoring baseball that the early tobacco and caramel card issues were built around.
