This is much better than photos convey--there's a real energy and palpability to the inked mark-making, and a real sense of immediacy to the whole thing; I actually tried for several minutes to walk away from it, because it was not inexpensive, but I simply could not! I find something quite poetic and metaphorical feeling about the phrase "slow line strokes," too, and the hand that wrote it and drew these lines feels very Ray Pettibon in manner to me. Anyway, a satisfying thing, surely done for an art/design class (and with a rendering of a sofa and chair on reverse) but I do think quite transcending the context of its making.
14 1/2" x 11 3/4". Black ink on board, signed M.Union it looks to me. 1940s/mid 20th c. I believe. Some loss to upper right corner and various smudges and scuffs around the border.
