Original German WWII-occupied Kotor cover, with Deutsche-Militaer-Verwaltung Kotor overprint on Italian stamps, created after the capitulation of Italy and subsequent German assumption of their former territories. With Erceg Novi registration label, cancles, and receiver, expertized Dr. Dub. Rare cover with two 'DeNtsch' errors (the 'u' in Deutsch is inverted, making it an 'n'). Total CV EUR2130 as used stamps. Very rare on cover.
