This is a U.S. Marine Corps P56 OG-107 Utility Shirt from the 50's.
Unlike the Army utility shirts, this shirt has concealed buttons. There is a stain on the back, a red stain on the back of the right sleeve on the fatigues jackets, and overall fading. The USMC and Global Anchor stencil on the chest has been rewritten on top with what looks like a magic pen, perhaps because it has faded. The Marines often write their names with a magic marker, so this could be considered a correction from that time. There are no missing buttons and it is still in good condition to be enjoyed. Because it is a used item, it cannot be returned. Please understand.
