“Verunglückte Landung eines Seeflugzeugs” / Lozenge camouflage (by drakegoodman)
An as yet unidentified type of seaplane (or float-plane - depending on which school you went to) rests precariously atop one of the taller buildings near its base, mid to late 1918. Leaning out of the third floor window are a pair of Matrosen or sailors, possibly charged with the task of removing said aircraft.
Of note is the just visible “lozenge camouflage” on the aircraft’s tail. This camouflage was used from late 1916 until the end of the war.
