Part of a larger, multi-sport issue, the W590 issue was originally not listed in the American Card Catalog, named in later editions.  While the complete set includes prizefighters, movie stars, and other athletes, there are 41 known baseball players included in the set.  The cards were issued in horizontal strips, with the card images extremely close to one another.  As a result, the majority of graded examples have been graded AUTHENTIC by both PSA and SGC, with much border missing.  As is the case with many strip card issues, low-grade examples are the norm.
