Thanks for the good info on the cards Mikee. Interesting to hear one has a relation to the Coburg castle,something that I would of overlooked for sure.
Bill, the small lettering for the kriegsblinden card looks to be: Durch das gewulke bright sein light. Buch Hiob 3F V.11.
I liked this image because of the nouveau look to it and the blind knight-like victim with a look of disgust on his face as he clutches a crucifix as though it were a massive sword as his sheild lies behind him hanging on a tree. What the instrument on his back is all about I have no idea.
There seems to be some crazy looking script on the back with some figures and judging by the illegibility of it, I wouldn't be surprised if it written by another doctor.
Also a mystery to me is the correspondence and postmark are in the year of 1912 but under the image there is what looks to be 4 names with dates of 1914/15.
