A couple threads have been resurrected and started that don't catch the essence of our annual "favorite pick-ups of 2015". Feel free to post your favorite pick-ups of the year regardless of whether it was a goal at start of year, an impulse buy, result of scope change, etc. I'll start with some Goodwin & Co. glass plate negatives that Saco River Auction brought to market this past January.
Here are a couple Stump Weidman negatives that were used to issue the 1887 OJs with Detroit and then modified in 1888 to show his team change (New York).
I also acquired a couple of 1888 negatives of Bobby Mathews batting which together show the earliest images I'm aware of the Hillerich bat with a stamp that was previously unknown (the negatives have amazing clarity not captured in following scan):
J F HILLERICH & SON
216 FIRST ST.
LOUISVILLE, KY.
And last, but certainly not least, an N173 brown mount of Sam Thompson courtesy a trade with Jay Miller.
