An incomplete but annotated property sketch of the market square of Obertyn (Обертин, Obertin, אוברטין). The map is undated but related to an 1825 cadastral map of Obertyn, and likely dates from the period. Two panels from what appears to have been a single large sheet covering the market square. Highly annotated with business owner names and their goods or services type on most buildings; includes pencil and redline revisions and re-numbering for a later edition. The original map was cut, cloth-backed, and folded for portability. This historic paper map is preserved by the Central State Historical Archives of Ukraine in Lviv (TsDIAL).
