I dunno. I'm assuming it was a choice as well; if I, an better-informed-than-average fan with Internet access can take 2 minutes and check the HoF's website or the Cubs.com shop and find the correct hat, I would have a difficult time believing that the Cubs themselves or Majestic Athletic or Mitchell and Ness or New Era or whomever was involved with making the throwbacks couldn't do the same without blinking.
