I see that the first rules of Basketball are to be auctioned off today at Southeby's and are expected to bring two million dollars.
A while back, I was researching the origins of Baseball in the sporting paper Spirit of the Times and in the May 12, 1855 issue came across these rules, which I believe to be the earliest published. I've never seen another or an earlier account. A nice history of Porter and early American sporting magazines appears here:
The first image of Baseball as we know it appeared in volume three of Porter's Spirit of the Times in 1857.
Less than three months to spring training!
