The article is 2 pages in length (on one single sheet of paper, front and back) and includes a few small black and white images diagrams the text.

As with most vintage magazine clippings, there is some yellowing to the paper due to age as well as light wear and small bends.

The magazine article was carefully removed directly from a Swiss magazine. It is not a copy or reproduction. The rest of the magazine is not included.
