US Navy USS Eisenhower Petty Officer Tropical White Short Sleeve Shirt 42" Chest - Nice condition Navy shirt with patches including Petty Officer 3rd Class Fire Controlman. 65% Polyester, 35% Cotton named to one J. M. Tamony. Proper ivory white color, the photos are what they are. Very soft woven fabric not twill. I don't know the age of this shirt, not too recent but not very old either. The size tag inside the collar says Medium however the chest at armpits measures 21" across so I don't know how they get medium out of that.
