I have a Durant sales booklet with the name Poertner Motor Car Co showing models of the early 20s. I'm not a collector or dealer but I wonder if any of your members might be interested in it?
1) booklet is 6 x 4 3/4, 12 pgs, sepia
2) it contains descriptions of touring, roadster, sedan, and coupe models and a specs page.
3) the back cover identifies "Poertner Motor Car Co" of NY & NJ
4) I would call it's condition 'good'
5) I can find no date(s) but I'm sure it's early 20s
6) I have no idea of its value and will consider any bids
