Gas and flame in modern warfare

MAJOR S. J. M. AULD, M.C.
Lieut. W. G. Thayer, of the Gas Defense Division, U. S. Army, is the artist of the drawing here reproduced which was designed for the purpose of bringing home the necessity of care in all that pertains to the use and manufacture of the gas mask.
In order to impress upon the soldier in training the need of care and speed in adjusting the mask in case of gas attack, the poster was printed with this wording:
KEEP YOUR HEAD; HOLD YOUR BREATH,— BE QUICK!! AND THIS WON’T HAPPEN TO YOU
That the workers engaged in the manufacture of gas masks might realize the importance of care and flawlessness in their work, the same poster was placed in the factories with a legend reading:
