We bought this from a lady who owned a Chevron station in DallasOregon.  It is a very rare book from 1947.  We have a couple of other Chevron books in our store, happy to bundle them together to save you on shipping.  
 
This is a neat vintage Chevron book that we like because of the early advertising, graphics, and also if you are recreating a Chevron store, or like the Chevron wings logo, this is a nice and rare add to any collection.
