Gotham Fans is a collection comprised of eight pennants commemorating various sports teams that originate from Gotham City. These pennants can be obtained from collection nodes found in the East End district of Gotham City.
"One of the biggest rackets in Gotham is illegal betting. The fake jersey numbers on these team pennants you've collected are most likely illegal bets. Good work uncovering the scheme."
"Each of these Gotham sports pennants you've collected is marked with an encrypted and illegal bet. I quite easily broke the code during my last nap. I'll think I'll use this information to make a few bets myself. Nice, associate."
