Hello i am new to this sit but i thought that it might help me find out some info about WWII since my grandfather was in the air force at the time. my question is dealing with a thing that i believe is called a blood check. it is a peice of leather that has an american flag, a flag that is all red and where the stars would be it is blue with one large white star, and a flag that looks like a police badge. it also has three different writings on it that i think are japaneese, chinese and possibly korean, but i am not sure. i thought i saw this same thing on the history channel one day and they said it was a blood check that a soldier would cary on them and if they were captured they would give this to the one who took them prisoner. supposidly its says something along the lines of "if you release me with no harm done there will be a reward from my government". thats what i remember from the boob tube. if anyone has any information on this please let me know thanks nick.
