Nice photo postcard showing front of the photographer's ship and another in the distance.
Written description on front “Sicherung beim –inesuchen” and written on negative LL '172'.
Stamped in red on back '--- von obermatrose BAUER' 'Obermatrose = top seamen'.
May or may not be related. There was an Obermatrose Max Bauer on the light cruiser SMS Bremen that sank after hitting mines in the Baltic sea in 1915
