Mystery Lajoie Card in Legendary Auction

[Hankphenom]

This "card" was cut from a mailer sent by the Felix Mendelsohn company of Chicago to solicit advertisers for the backs of their baseball player card set of 200. I have the complete mailer, which contains a horizontal strip of six players: Nap Lajoie, Heinie Zimmerman, Grover Alexander, Johnny Evers, Eddie Collins, and Honus Wagner. The paper stock is heavy, but I don't know how it would compare to the M101-4 and M101-5 cards it is soliciting advertisers for. The printing font is apparently different, too, so perhaps this mailer was made before the set itself was produced. Under the strip, which makes up one side of the broadside when folded for mailing (the other side has lines for the address and a stamp box) is the question: "These men are better known to the majority of your prospects than Thos. Edison, Henry Ford, Sec'y Lansing, Marconi, Lord Kitchener, or Von Hindenburg. Why?") The broadside inside goes to great lengths to explain why. I'd include a picture, but don't have a scanner. I'll bring it to the Valley Forge show in June if anybody wants to see it.

By the way, what did it go for? I can't seem to access last night's results, even when logged in. Why is that?
