The dimensions of the base poster are 17-3/8" x 31-1/2". This is meant as a certificate to show a military members posthumous, and post injury honor for valor and distinguished performance on the battlefield. According to the library of Congress's website, this poster shows Columbia holding a proclamation above her head in one hand while touching a sword to the shoulder of a World War I doughboy who kneels at her feet with the other hand.
A large sized US flag flies behind her along with the faces of other soldiers. It then goes on to say that they are inscribed with the name of the intended military member and their regiment. The recipient in question is Carl A. However, I'm unable to determine rank and regiment due to me not being used to the font.
