The postcard was sent in 1918, i.e. was published before 1923, thus making it public domain in the United States.

The back of the card mentions M. Glückstadt & Münden, Hamburg as the publisher. Searching this term in Google didn't bring up anything relatable. Also, there's a word on the back that I read as Gravoryta. Chucking that into Google once more didn't return a single result. Since neither word on the card allowed me to identify the author and the first release is more than 70 years ago, I regard this file as public domain in Germany too. Please notify me if you think differently. Cheers, Benutzer:Christallkeks.
