On 1 July 1990, people queued for currency exchange outside a savings bank in Wanzleben, Saxony-Anhalt. That was the day the treaty establishing monetary, economic and social union between West and East Germany—signed on 18 May—entered into force. The Deutsche Mark became the sole means of payment in East Germany. Photographer Günter Zint documented the crowd at the bank on the day of conversion. The archive does not state individual waiting times or exchange amounts. It does show a treaty becoming a physical sequence: citizens standing in order to convert old money into the currency of a new daily economy.
