WW1 Imperial German flag first world war army antique old original French

Description

WW1
Original captured French or possibly a German Imperial Flag
Minor rips mostly on red and black portion, many tiny and a few larger holes all over. Fading
throughout. Some staining. Piece of red part was torn or cut off
Nice historic flag aside from the damage listed
Was stored folded for a long time
The shape implies it's French, but colour is faded. I believe this is a French flag captured by a WW1 German soldier
approx. 27" x 19 1/2"
