All city: New York 1947-1957.

Try it.  Name teams for each position each year from among:
New York Giants
Brooklyn Dodgers
New York Yankees.

Include one lefty and one righty starting pitcher.  And a manager.  Should be fun.

Try it for other cities for other eras.

I'll take a crack at it in a future post.
