The contract signed by Lou Gehrig at the beginning of his first full season in the major leagues is going on the auction block. Steiner Auctions says it will offer the pact on consignment in its Fall Classic catalog, set to open for bidding in mid-October. Gehrig, 21 at the time, signed the document “H.L. Gehrig”. It’s stamped on April 16, 1925, the day of the Yankees’ third game of the season. It’s also signed by Yankees executive Ed Barrow, who also signed for team owner Jacob Ruppert.
