Here are the Two Curly W books:
2012 Washington Nationals Media Guide
Just like it says it is the "yearbook" or rather the Season Preview from 2012 for the Washington Nationals. 2012 the year they first went to the playoffs.
The Ultimate Washington Baseball Trivia Book by David Elfin
Again a self-explanatory book. Written in 2004 after the announcement of the move of the Montreal Expos to Washington DC.
