If there has already been a discussion on this, and I missed it, then my apologies. This seems to be such a huge item, that it's worthy of talking about. (Official Runscott Disclaimer: I'm not questioning its authenticity)
This just sold in Clean Sweep for $71,348 plus the juice. I was amazed to see such an item in handwritten form - they generally typed such documents; for example, here's another 1918 contract also signed by Ruth and Frazee:

I realize that amendments, addendums do end up as handwritten notes, so again, I'm not questioning authenticity. In fact, they are both dated January 11, 1918, so it makes sense that the handwritten one could have been a result of additional negotiations, that was quickly drawn up during signing of the typewritten one. Here's the link to the Clean Sweep handwritten one:

Below are both the typewritten version, and the handwritten Clean Sweep one.
