Bulletin Display Racks for Extension Workers. E-book. Formato PDF Lyman J. Noordhoff   -  Forgotten Books, 2017  - 

Because the subject was of interest nationally, the author offered to gather further examples and write the copy. Upon direct inquiry, about a dozen exten sion editors sent information or pictures on other types of display racks. As with everything worth while, this publication is the result of contributions by many persons. Usda has no drawings or construction plans for these display racks.
