Listed here is this memo booklet with pictures and advertising by Rex Chain Company.  The book is also stamped by a local company, Winn Supply.  The book has several high quality depictions of Rex products and consists of about a dozen blank pages, perforated at the base.  A couple of the sheets were manually lined by the previous owner and has customer information.  There are also some missing pages where sheets were torn out.  Please check the pictures and contact me if you have any questions.
