SABR has tweeted a link to an ebook on the Tony C Award, and in so doing has made public one of the few color images of Conig during his ill-dated comeback with the 1975 Red Sox.
This is - naturally - a Doug McWilliams image from the Hall of Fame library and though the background has been stripped out, it's still useful in filling a void.
BTW this is the link to the SABR ebook
