The seller admits it's Harry Wilson in his description (addendum from 11/29 at the bottom of the text). Someone just overpaid by roughly $1,450 (so no big deal)
Edit - Lance beat me to the description part. Hopefully the "winning" bidder (and I use that term loosely) has some recourse, or can retract his bid (based on the shilling and the faulty descrition). The final shilling raised the price over $550.
