CHUNG Ling Soo (W.E. Robinson, 1861 ? 1918). Chung Ling Soo. A Few Facial Expressions During the Fire Trick. Birmingham: James Upton Ltd., ca. 1908. Twelve bust portraits of Soo with different comedic expressions fill the image, bounded by a printed wooden frame. 30 x 20". Linen backed. Minor over-coloring to borders. A-.Soo's mouth and teeth were so damaged by his Fire Trick ? in which he lit cotton batting ablaze in his mouth, then produced sparks, black soot, and eventually ribbons and a barber pole from it ? that the portraits on this poster (and others) do not show him smiling for the camera.
