This panel sold at the recent SCP auction here:

I did not win this auction, which described the lot as c.1915-1919 with Babe Ruth, Eddie Collins, Edd Roush, Rabbit Maranville, Tris Speaker and Eddie Cicotte. Out of curiosity, has anyone seen something like these before? Also, did the auction house get the dates and players correct? I know the Ruth is obvious, but on some cards, he has been shown in his Red Sox uniform even when he is with the Yankees. For the player list, I know SCP originally even had Joe Jackson as one of the players on the panel before they eventually corrected it.
