N.p. S.i. 1937. Large and colorful union shop sign, prominently featuring the I.W.W. logo at center in front of the red flag of communism, with the captions "Education, Organization, Emancipation" and "One Union, One Label, One Enemy" at upper right and lower left corners. An attractive example of Henkelman's work - a signpainter by profession, and occasional cartoonist for the I.W.W.'s General Organization Bulletin. Original hand-painted shop sign, composed in oil on board, measuring 48.25cm x 88.25cm (19" x 34 5/8"); signed and dated in red paint at lower right corner: "Henkelman / Aug.1937." Small hole for hanging drilled at center of upper margin; some wear to extremities and corners; surface dusty, with a shallow, jagged 10" scar to lower third of the sign; board is sound, and otherwise well-preserved.
