Confederate Patriotic Cover

Please see the attached images. Is there anything wrong with this cover? What is the value expected? Thank you in advance.

Thanks for posting the full cover. Anything on the back? Post a close up of the stamp itself. My request is kinda funny because usually people post just the stamp and we want to see the entire cover.

Is there a cancel of any kind on the stamp? If not then that would raise a question in my mind. Is there anything on the back? In the second photo there appears to be a 3/4 inch horizontal band or tape or something about a quarter of an inch from the top. What is that? I can not make out the name of the city in the address - it looks something like Besent or Besenk or ??? What is it?
I am not an expert on Confederate patriotic covers, but is this pattern one that is known and was it available in the area where it was sent? This is the sort of thing that I would want to have expertized before getting my hopes up, especially since Confederate covers have long been heavily faked since authentic ones bring high prices. I hope it turns out to be real as I think it looks nice.

Your flag is a highly unusual design. It is not listed or illustrated in the Confederate Handbook published in 2012. Is the design directly printed onto to the envelope? The vertical lines in the red portion of the flag do not appear on any other 7 star flag. I do not have access to Milgram's most recent work which may be more comprehensive than the CSA Handbook, but I find your flag highly unusual and questionable, but not impossible.

Yea I get the same feeling and the cover looks fake with a stamp just affixed. It was on ebay.

The two blank boxes at the right of the flag are normally printed white and the right edge is normally a straight line. Could this be a cut and paste job? I did a checking of the Siegel and PF web sites. As I thought the seven star flag is very uncommon with the Scott 11 as the seven star flag is from the very beginning of the War. Mostly used in 1861 and changed as states were added to the CSA.

Thank you great info. for $350 should I keep it or give it back to the seller?
