A Discarded Treasure

This is a tiny little book...only 3" x 4" and I found it at our local book fair.  And I'm sure you're wondering what is so spectacular about this book.  It was published by a company called Papier-Mache Press.  Of course, I love the title.  And inside the book, it was inscribed, "In the night, I am reading these to you."  So, I believe this was from a wife to her husband.  It is a collection of poems by different people with titles like, "To the Husband Who stands at the Sink, Intent on Shaving," and "For an Anniversary," "Front Porch Partners."  There are lovely, sepia tone photographs in the book.  So...my question is...how did this special little book end up in a book fair?  Based on the inscription in the book...had the wife purchased this book after her husband had passed?  What is the story.  I only know, that if it had belonged to my grandmother or aunt or mother....I would have found a special place for it, tucked away safely in a drawer....but now it's my treasure and it is safe.
