Here's a flag from my collection that was brought home, or sent home by a Kiwi veteran. The vet was with 'A' Company, 35th Battalion, 2nd NZEF. The flag was taken on Nissan Island, which is part of the Green Islands group, in February 1944.
This flag is a little un-usual because the vet has outlined the kanji with an ink pen.
The vet also wrote his details, and where and when the flag was taken.
The best part about this item is this photo of the vet holding it. The Kiwi vet is on the right. On the left is an American vet. I have both names of these guys. The Nissan Island operation was a joint Kiwi/American venture.
In the photo above, the vets are holding the flag this way.
