Looky what I found...
Never was able to find another image of White Sox pitcher Jack Kucek in thew orangish-reddish hat that was their pre-Veeck uniform. All we had was the dark headshot on his 75' Topps Rookies card. Pretty apparent that this is that photo, but a much bigger crop and from and B&W team issued 8x10. Was able to get Kula to colorize and it looks a bunch better than the Topps version. No watermark, not a Vault image.
