This rare 1944 Slovenia Laibach German Occupation postage due set presents four distinct values produced during one of the most turbulent phases of European wartime postal history and illustrates the administrative transformation of Ljubljana under German control. Issued as official postage due stamps in 1944 for use within the Province of Laibach these issues were created through photogravure printing on Italian postal stocks and display the characteristic crowned watermark type 11 which reflects the continued reliance on Italian production methods after the collapse of the Italian administration. The set comprises the 30 centesimo in deep blue violet Michel P5 the 40 centesimo in brown yellow Michel P6 the 50 centesimo in dark violet Michel P7 and the 1 lira in red orange Michel P8 each featuring the overprinted imperial double headed eagle emblem symbolising the German imposed authority combined with the overprinted value inscriptions denoting their function as official dues. These stamps were printed in limited quantities with documented print runs ranging from just 87486 for the 1 lira value to 500943 for the 30 centesimo reflecting significant scarcity today particularly in mint condition. Beyond their technical attributes these issues embody an important historical narrative of occupation administration propaganda and the restructuring of civic systems during wartime. Their bold overprints and strong typographic compositions give them lasting visual strength while also providing context for the postal mechanisms imposed in Central Europe during the final year of the conflict. Surviving mint examples with intact perforations and strong colour retention such as this set remain highly desirable among collectors who specialise in WWII occupation material and Central European philately. Estimate "$450 – 650".
