Postcard of a large group of United States army soldiers at a camp in Maryland, possibly Glen Bernie or Laurel. They are all in their military uniform, gathered in multiple rows. Behind them, a series of tall leafless trees can be seen, as well as a single-story structure in the very center at the top of a hill. There is printed text on the front that reads "47 Battalion 23rd Engineers, Glen Bernie, MD. Feb. 1918." There is a black arrow near the top of the image pointing at an individual, identified as Arnold G. Knock. This information is verified on the back of the postcard, on which Arnold himself, under the "correspondence" heading, wrote: "I am in this picture the arrow point is our my head Did you receive my letter Hoping to hear from you soon This is my address Arnold G. Knock, Laurel Maryland, Truck Co #10 23 Engrs. [sic]" He has addressed the postcard on the left and right to an Emilie Andersen at "El Campo, Texas. D. S. R. #55."
