Mary L. Martin owns the world\'s largest postcard shop. And just just recently wrote (with Q. David Bowers) A Guide Book of Collectible Postcards. We talk about the process that led to the writing and publication of the book, and then talk about the postcard collecting business in general. You can find Mary\'s book along with millions of collectible postcards at marylmartin.com.
