Here is a brilliant NSRL (Nationalsozialistischer Reichsbund für Leibesübungen) standard that measures 56″ x 43″.  The NSRL was the German League of the Reich for Physical Exercise.   This particular example is for a football club in Rhein region in Prussia.  It’s in spectacular condition with very few moth nips that don’t detract from it whatsoever.  All of the mounting hardware is perfectly in tact.  The corner patches measure 11 1/2″ x 7 1/2″ and is chain stitched “Gau XI Futzball Verein Preußen Beuel – Rheindorf”.
