And I've been researching for over an hour, trying to find out its title and when it was printed.
What I've found out so far is that the original painting was made by Josef Julius Durst, who lived between 1878 and 1950. The print was then distributed as a post card by the Metz brothers and their company.
The writing (top right) means:
"In all storms
In all need"
(Top left)
"He will shield you
The loyal God"
(Bottom)
"Knightly grapple, motherly praying, helps defeat the enemy, solves all distress!"
As german is my first language, this was easy to translate, but I can't find any trace of the title.
I could post a higher resolution, but this would take a while.
