Mike is the absolute foremost authority (still living) on Southwestern American Art. Anything he thinks is work publishing is worth collecting if you value your knowledge of the genre. He is also one of the coolest dudes you will ever meet ... if you are that lucky.
This one is kind of a coffee table volume. Glossy stock, hard cover and fully 8.5" x 11"
