WW1 German march 1917 dated postcard

A very nice WW1 German postcard that shows a women with a crest and the text (roughly translated) “God protects you”

On the back the card is written.
Hard to read and translate, because it is written in old style German.
Card is probably posted in France or Belgium.
It has a stamp with (hard to read) “1 reserve infantry battalion …. comp.”.
Card is dated with the date stamp 4 march 1917.
