WW1 Imperial German Map Marked To The 143rd ( 4th Lower Alsacian ) Infantry Regiment , XV Army Corps

This German map has map number & regimental marking ' 12 C JR143 ' for the 143rd Infantry Regiment . They were an Alsacian regiment raised in 1890 & part of XV Army Corps. Interestingly this map depicts the area from where the regiment were raised... Strasbourg , Mutzig. No dates on the map however it is unlikely that it would have been produced in the post WW1 period.
