Simeon Roode Munger m. Polly Ann Cain

I bought an old book in Oklahoma City that is signed by Polly Ann Cain, Simeon Roode Munger, and Milo W. Munger. I would be interested to know how this book got to Oklahoma; I understand that these Mungers lived in Elkader, Iowa.Do you have any information for me or want to see the book?
Thank you!
