Korean War Blood Chit / Distressed Cotton

I'm not really sure of the material originally used for this Blood Chit but we've done ours on a substantial weight cotton just for durability. It's backed with a nice weight as well making this suitable as an inside map pocket as commonly rigger modified into Flight jackets from WW2 and on. It is already slightly aged being off white but will take on it's own character rapidly being an absorbent material...
