Here is a very strange discovery that some Batman Collectors might find interesting. Right now there is a Bowling Supply Company out there marketing Bowling Balls and Bowling Pins with Batman-themed graphics ( comic book version ).
They make 9 different Bowling Balls that not only feature"Batman" but some are geared towards Robin, Batgirl, Joker, Penguin, & Bane. The same format goes for the Bowling Pins as well. The Balls go for around $120 each and the Pins are $70 each. They even sell a "Batman Bat-Symbol Logo Bowling Bag" as well ( $70 ). I have only shown a few examples here to give you an idea but to view the entire series please CLICK HERE!
