Though the earliest card of Hall of Famer Harry Heilmann is his 1913 Zeenut issue, the 1915 card is quite a rarity. Just three examples have been graded - this, a PSA 4 and a BVG 3, examples of a card that many advanced collectors have never seen before. This example is, as we would call it, "well worn," with significant staining and paper loss throughout.  The reverse is heavily stained by moisture, some of which has bled through to the front, most noticeably in the upper-left corner.  Distinctly collector-grade, and desirable just the same, an extreme rarity.
