Here are two pages of articles titled, “The Practice and Theory of Aviation – II”. The articles discuss modern aeroplanes (of 1910) and include illustrations of the Wright Biplane and two types of Voisin Biplanes. I scanned these pages from the October 29, 1910 issue of the Scientific American Supplement No. 1817. Part I of this article on biplanes was published in the Scientific American Supplement No. 1816. I don’t own that issue.
One of my adult sons is going to have the original size scans of these pages professionally printed and custom framed for a friend of his who is a pilot/owner of a small plane and vintage plane enthusiast. I love his idea and thought some of you would like to have these original size (10” x 15”) graphics to do something similar, whether for a friend or for your own enjoyment. 
Here are black and white clip art images of the three biplanes from the pages.
