Original large archive of approximately 370 vintage 35 mm color slides, housed in four original slide magazines, dating from the late 1960s. The images form a coherent and extensive documentary record of daily life, military presence and humanitarian activity in the Middle East, very likely connected to United Nations observation or peacekeeping missions. All slides appear to have been taken by the same photographer during a limited time period, resulting in a consistent visual style and strong narrative continuity. The archive includes military personnel, UN-marked vehicles and ambulances, bases and logistics scenes, urban street life, rural and pastoral settings, historic architecture and archaeological sites, as well as a small number of rare documentary images of field medical and surgical activity related to emergency or military medicine. The majority of the slides are mounted in high-quality glass mounts with protective glass on both sides, ensuring good long-term preservation and flatness. The remaining slides are original Kodachrome transparencies. All are original period materials, not later reproductions. Color saturation and contrast remain good overall for age, with normal signs of storage such as light dust or minor surface marks. No heavy fading observed. Slides are sold in original condition, uncleaned and unaltered. This is not a tourist or souvenir collection, but a substantial historical archive with clear documentary and research value. Due to the size, coherence and subject matter, the lot is particularly suitable for collectors of historical photography, United Nations material, military and humanitarian history, medical history, or Middle Eastern studies.
