I saw that lot, but what caught my eye was the card next to the Butler...a T206 of Kelley that had the cool 'William(s) - St. Louis' transfer on the back. I believe this is Jimmy Williams who ended his MLB career playing for the Browns in 1908 and 1909, and that the transfer is possibly from the German Baseball stamps issue of 1909-10, which includes Williams. This set is detailed in this link from the Prewarcards website:

I have included a scan of the back of the Kelley card. I guess we all focus on what interests us, because I didn't even notice the Butler card. I have to admit I was wondering why this lot went for so much, because I couldn't imagine it being much more than a $800 lot, even with the cool back transfer card.
I guess I know now.
