Lefty O'Doul Brooklyn
Charlie Klein Philadelphia
Dazzy Vance Brooklyn
In terms of card stock, the W517 minis are printed on a coarser, darker, thinner chipboard than the exhibits. I've held them up together and compared.
It is easy to differentiate cuts of 4 on 1s from the 1930s from the W517 mini/4-on-1 PC back. The latter have handwritten identifying information; all of the 1930s exhibit issues have typeset information.
While the Gehrig configuration stated above is accurate, it is theoretically possible that the backs will be found with any number of partial or different configurations depending on the idiosyncracies of the printing run, including reversed direction postcard backs. I have some PC backed cards with the PC back printed very badly off center. The QC on these products wasn't great.
In terms of known 4 on 1's of the format matching W517 mini, I have the following confirmed (players listed clockwise from upper left quadrant):
Gehrig-Grove-Donahue-Cochrane
Judge-Waner-Kamm-Jackson
O'Doul-Vance-Shires-Kritz
Bear in mind that there are at least a few other 4 on 1's with boxers and baseball players combined. The fronts are differently captioned but they are out there. I think our peerless leader has one from a Verkman auction last year that was sold as a strip card.
