Query: A Self-Portrait in Post

These letters provide a more intimate look into the person of Vincent van Gogh than any college course you'll ever take. In going through the book, the reader gets a real sense that by the end the whole is greater than the sum of the parts. This collection isn't an oversimplified summary of a life, but rather a look at Vincent as a complicated soul with many layers to his personality, like most of us.
