Wow.  What a year it was.  Looks to be 1958 since it references first year sales and the Edsel was introduced in fall 1957 as a 1958 model year car.  Awesome cutout shape to this piece.  Just a simple fold-open brochure designed to be put in a regular legal envelope.  Came out of my folks house.  I can't find any others like it on ebay so I figure this was a local dealer effort, not some piece of national advertising.  Hoping to find it a good home with an Edsel owner or someone with fond memories of the brand.  Good luck and thanks for bidding!
