It could be called the Ten Commandments of Major League Baseball, even though it’s 74 pages long. Or perhaps, since it has just been discovered, it could be baseball’s version of the Dead Sea Scrolls. Regardless, the 1876 “Founding Documents and Original Constitution of Major League Baseball” are a valuable piece of sports memorabilia. The documents will go on sale May 24 in online bidding sponsored by SCP Auctions.
