A superb, black, proof impression, apart from the published editions, on tissue-thin cream laid Japan, with full margins ( 7/8 to 1 5/8 inches), in excellent condition.
Feininger estate stamp in the bottom right sheet corner.
This print was also titled by the artist Segler, Segel-Schiffe, Kreuzende Schiffe (and that's the title he used in this impression), and Ships.
Prasse notes that there were proofs made on carbon copy paper and Kozo and other Japanese laid paper (the latter two types were Feininger's favorite papers).
