W590 is primarily a 1920's strip card issue that persisted into 1931, produced by an unknown manufacturer and featuring what looks like news photos of roughly 75 players across multiple sports, in an somewhat low resolution back-and-white reproduction. Not even catalogued until 1968, the set is primarily known today for having hard-to-track down cards of Lou Gehrig, Ty Cobb and Babe Ruth.  The cards were issued in horizontal strips, the cards extremely close to one another.  As a result, the majority of the graded examples have been graded AUTHENTIC by both PSA and SGC, with much border missing.  As is the case with many strip card issues, lower-grade examples are the norm.

PSA has graded 17 Gehrigs, 14 of which are graded as PSA Authentic, just as this one is. This example shows an irregular cut from the original strip that's especially noticeable at the bottom, which lacks the team and league designation in the third line of copy that is typically seen with these cards.  Still, the image of Gehrig is nicely, if not remarkably, well-preserved and looks about as strong as anything can from a set that was clearly issued without much thought given to quality control.  As the hobby begins to delve into more obscure cards of its greats, the W590 Gehrig stands out as a card that is rapidly increasing in value.
