For what it's worth, I've looked at about a dozen signed player contracts from the 1910s (using Google), and none that I've seen so far have the club president's name typed out - they all just simply have "president" typed, or often just handwritten, under the president's signature.

In fact, a lot of the ones I've checked look pretty sloppy and informal by today's standards, with mixtures of upper and lower case type, handwritten additions that aren't initialed, signatures that aren't notarized, witnessed or dated, dates typed or written above or below the appropriate sections, overlapped writing or type, etc. My impression is that baseball contracts of the 1910s weren't nearly as formal, detailed or precise as baseball or most other contracts are today (that's assuming, of course, that not all of the contracts viewable on line are forgeries).
