This is for a vintage 1978 sales catalog for park shelters and encolosed buildings, with additional inserts, including a price sheet and a cover letter addressed to the then Battalion Chief of the Arcade Fire Department in Sacramento, CA from Poligon a division of W.H. Porter, Inc. Fantastic reference piece of structures that would be commonly found at parks in the 70s! Cover letter has some toning, and all other pieces are clean and nice. Front cover of the main sales catalog has a few specks of dirt on it just above the title.
