Presented is a modestly graded sample of Philadelphia Phillies infielder Otto Knabe from the E104-3 Nadja Caramels set, one of the most distinctive, unusual, and important rarities of all 1910-era caramel-card issues. These cards are often confused with similarly designed "E" card and related sets (especially E104-1 and E104-2), but are distinct, featuring designs that are unique to this set, and therefore have an enormous significance to 1910-era cards and caramel cards in general that is often overlooked by collectors, probably in large part because all cards from this set are so incredibly rare. To date, thirty-seven different subjects are known, featuring players from five different teams (mostly Tigers, Phillies, and Giants players, but one Cleveland player and two Cardinals are also known). Encapsulated as Authentic by PSA, the offered example displays minor creasing, evenly rounded corners including the lower left missing, and light soiling. The desirable advertising reverse, with a boldly printed Nadja Caramels advertisement, has been impacted by paper loss from album removal. (These cards are also found with blank backs.) A presentable sample of a significant caramel-card rarity. Reserve $200. Estimate (open).
