"Ohne Fleischmarken: Von den spartakisten im strassenkampf erschossenes pferd wird von der armen bevolkerung ausgeschnitten."
Translates to: "Without meat-tokens: a horse shot in a streetfight by spartacists is being butchered by the poor populace."
This is a photo taken during the German inflationary period. There was no food so the people are butchering a horse that died in the street to eat. People are standing around it with knives waiting their turn to carve off a piece for their starving families.
If anyone can read German cursive I would love to know what it says on the back of this postcard. Please post a translation in the comments if you can make it out. You should be able to make it out better if you click on the image to enlarge it.
