International Cooperative Project “Reframing Images of Mongolia: Photographic Records from the 19th Century to the Early 20th Century” (Japan Society for the Promotion of Science, Grant-in-Aid for Scientific Research (A) Project/ Number: 17H00897) supervised by Prof. Yuki Konagaya from MINPAKU in Osaka in collaboration with Prof. Agata Bareja-Starzyńska. The main focus is on photographs that require adequate description. The provenance, dating, and authorship of the photographs can be established on the basis of handwritten descriptions on the verso, travel notes, letters, and various other documents. Among the photographs used in the project are those produced during the 1912 scientific expedition, currently forming part of the legacy of Professor W. Kotwicz at the Archive of Science of the Polish Academy of Sciences (PAN) and Polish Academy of Arts and Sciences (PAU) in Cracow.
