Hamann's fine Expressionist portrait of his close friend, poet and writer Richard Dehmel. Hamann (primarily a sculptor) was Jewish, as was Dehmel's wife, and they were active in the same social and artistic circles.
On fine Japanese tissue.
Signed by the artist and justified "Handabzug 20" (hand-printed proof no. 20).
In excellent condition, with some minor marginal flaws.
