Bavaria 1920 2-Mark 'Patrona Bavariae' Stamp with 'Deutsches Reich' Overprint

This is a rectangular postage stamp from the historical German state of Bavaria (Bayern), originally issued around 1914-1920 and subsequently overprinted. The central design features the 'Patrona Bavariae' (Maiden with Child) motif set within a circular frame on a purple/violet and brown background. The top of the stamp is inscribed with 'BAYERN' and the bottom denotes the denomination of '2 MARK'. A notable feature is the black typographical overprint reading 'Deutsches Reich', which indicates its use during the transition period of the Weimar Republic after the Bavarian postal authority was integrated into the national postal service in April 1920. The stamp has perforated edges, which appear somewhat uneven or 'shaggy,' common in early 20th-century philatelic items. Its condition shows signs of aging, including toning/browning of the paper particularly along the edges, and a faint circular cancellation mark typical of post-use specimens. The print quality is consistent with late imperial intaglio or typography methods, showing a detailed central icon surrounded by a decorative border. This specific variety represents a significant historical era in German philately, marking the end of Bavaria's autonomy in postal matters.
