fkwThe name W511 is from the old "American Card Catalog" (just like T206, D303, R319 etc.).
When the Ruth card was first listed as "1924 W-Unc." a few years back in the Standard Catalog of Baseball Cards, they didnt know where it was from or if it was actually part of a set, or if the set was named already. Well it was..... it is W511. One day the Catalog will update the listing and put it in its true strip card set, and update the year to 1926 (With known movie star cards, there are movies named on the card that date it to exactly 1926).
