Of course, as soon as I finally make a photochopped George Foster / 1886 White Sox post... I discover an actual image. This image is currently available from the Tribune archive on eBay recording Foster's only home run during his short time with the Sox at the end of the 1986 season... and it looks like he is using his trademark bad-ass black bat.
I don't feel that bad, because the above image is not that clear and not something I would attempt to colorize and use on one of my cards. The 348th (and final) home run of Foster's career came on August 15th, 1986 at Comiskey Park, in the 4th inning, off Milwaukee Brewers pitcher Bill Wegman. It only was Foster's second at bat in his first game with the Sox, after unceremoniously being released by the Mets a week earlier. Sadly, it was the only real highlight of his short time in Chicago. He would have another 52 plate appearances over the remaining 15 games and collect only 10 more hits before calling it a career and riding off into the sunset.
