These items are made with an American flag image that I created myself, based on historical sources. I made the image specifically for this purpose so that it prints very well. I've ordered a number of items for myself and I'm very happy with them.
See this American flag history page for more information about the U.S. flag. You might also be interested in my other CafePress flag shops:
