Lost paperback edition of 'To Kill a Mockingbird' left on a bench near the Lincoln Memorial at the National Mall in Washington DC.

I lost my paperback edition of 'To Kill a Mockingbird' while visiting the National Mall in Washington DC. I was sitting on a bench near the Lincoln Memorial reading it and I think I accidentally left it there when I got up to take pictures. It's a well-worn copy with my name written in it, and it means a lot to me. If anyone finds it, I would really appreciate getting it back!
