German WW1 Hospital Military Nurses Sent By Soldier War Mainz 2x Postcard

bg882 Antique pair of 1915 and 1916 rare German wartime postcards, onefrom Mainz of a German medical station during fighting and soldiers with leg wounds etc being attended to by nurses - Condition shows ageing but only slight handling so graded good plus though be aware used a used appearance (which of course it is) - One soldier struggles with his legs damaged as the nurses lead him down the stairs - The old fashioned car to the right could be of great value to a transport postcard collector - This was sent by a soldier and the Mainz frank dated 10th December 1916 - The second is a map postcard in similar condition but what makes this card collectible I believe could be the reverse as it is a military message from a war camp dated 23rd March 1915 (see scan) -  I have scanned this & the other message from the soldier to view (see image 2) for if someone can translate as it could prove a message direct from the frontline - Please see all my cards from this collection as many were sent by German soldiers during the war from WW1 camps with postmarks of the camps and war messages on reverses.
