These items are made with a Navy Jack 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 NavyJack.info for more information about the First Navy Jack flag. You might also be interested in my other CafePress flag shops:

Yours in liberty,
