Can someone direct me? I understand the battle flag was square but today i see lots of rectangular flags. I saw a lecture that said the Confederate battle flag, so often waved today, did not exist till the early 1920's and then only because a rectangular flag was easier and cheaper to make. I have seen a few pictures in Harpers Weekly that show a rectangular flag. But never a historical "southern" source that describes or shows a rectangular flag. Might I assume the Harpers pictures are incorrect?
