Lot of 4 vintage color photographs, each measuring 6x4 inches, documenting a military base construction site, possibly a NATO base in Kosovo or the Balkans. A related photo in this estate's collection is marked 07/99 on the back, suggesting a July 1999 date, consistent with KFOR-era NATO construction activity in the region. Images show: soldiers in woodland camouflage walking past newly built barracks with a cargo truck parked nearby; four soldiers in berets observing a concrete-frame building under construction with a tower crane and insulation rolls stacked on site; a soldier viewed from behind watching construction with a crane and stacked brick pallets; and an unpopulated construction site with brick pallets, muddy standing water, and earthen bunker-like mounds in the distance. No captions or unit markings are visible on the prints. Print quality is fair, with some soft focus and minor color fading typical of the era; please review photos for specific condition. These photos are associated with the estate of USAF Col. Patricia Jane Harrington. A cohesive small set capturing a NATO base build-out phase, likely appealing to military construction, KFOR/Balkans, or Air Force estate collectors. Please review photos for condition.
