Are you guys suggesting that the various boroughs had their own racing colors? Or were the rivalries largely club based? If the latter, it's easy to imagine that clubs didn't attract much membership outside the borders of their respective boroughs, given how Balkanized the city was by geographic and ethnic divides. I have a friend who's a tugboat mate in the harbor there who says he met a guy who'd never been off Staten Island--and I don't doubt that that sort of thing used to be fairly common.
Me, I'd like to see a jersey celebrating Ecurie Ecosse, the Scottish auto racing team of the 1950s.
