Here’s what we can tell you about this sepia card:  it was mailed, because there’s a 1917 postmark (and date on the mostly unreadable message) but there is no sign there was ever any stamp on the front or the back.  Printed attribution:  “155 W.B. Levy, Hamburg Zensur Altona 527”.  Clearly from World War One.  We’re not certain how to grade this because of the stamp issue, but because the front is so good we will call it Grade: 2
