This Prioritäts-Aktie (priority share) of 1200 Mark No. 824 of Laederich & Cie, issued in Mülhausen (Mulhouse, Alsace) on 31 March 1901, is a direct testimony of the period of annexation of Alsace-Lorraine by the German Empire (1871-1918). Laederich & Cie was a partnership limited by shares (Commanditgesellschaft auf Aktien) with a capital of 2,040,000 Marks, as evidenced by this certificate issued to Frau Adrienne Laederich, likely a member of the founding family. This certificate presents several remarkable features for the collector: the German Gothic typography of the Wilhelmine era, the red fiscal stamp of the Reichsstempel (imperial stamp), and a blue stamp indicating the "Rückkauf des Vorzugsrechtes" (buyback of the priority right).
