A 12cm x 17cm, softcover, eighty-four page booklet, to whose red cover is the image of a disembodied head wearing a gasmask. "Gasschutz...Gashilfe gegen Giftgase" (Gas-defense...Gas-help against Poison-gas) is above the image, and "Merkbüchlein für Laienhelfer bis zum Eingreifen des Arztes" (Note-booklet for Novice-helpers until to-the Intervention of-the Doctors) is to the right of it. The indication that this is the twelfth edition, its price, authors, and publishing house are to the base of the cover. The text is divided into ten sections, and is profusely illustrated with eighty-seven line drawings. Most of the illustrations are either anatomical, or depict the functioning and proper wear of the various gas masks available at that time. Advertisements for other books on medical subjects are to the last page, both inside covers, and the back cover.
