What Jan said could work. If you want to I could just make a file of the original flag images I used to make the army cards.
Making (and selling) flag stickers for NIE has been on my "things to do" list for a while, but it doesn't look like I'm going to get around to it anytime soon, unfortunately.
I have the flags. They have already been applied to the pieces, but I could peel them off and have them scanned.
I would do this if I could get a set of new stickers for myself.
Let me know.
