The report has a green cover with a color picture of a woman and young girl who are listening to a telephone call while looking at a photo of an older couple who are probably the girl's grandparents. The interior pages include articles about company projects, products, and annual financial statements. One article on page 17 mentions the "Bell Solar Battery" which was an invention of the Bell Telephone Laboratories and was "the first successful device to convert useful amounts of the sun's energy directly into electrical energy." The articles are printed in black text on white paper and also feature black and white pictures.
