This is a 1969 first printing of the Petrified Forest, the Story behind the Scenery, by Sidney Ash And David May.  I went on a family vacation to see this in 1976, and purchased this magazine in the gift shop.  It's a wonderful 32 page book about the park.  Cool piece of history, still in great shape.  Colors look good, overall the magazine is in good shape.  Please look closely at all pictures to see exactly what you are getting.
