This is a vintage poster advertising a magic act called "Self Decapitation" performed by "Kellar." The poster features a full-body illustration of a man, presumably Kellar, seated on a wooden chair. He is depicted in a dramatic pose, with one hand raised and the other holding his head, which appears to be detached from his body. The background is a dark, shadowy orange, with rays of light emanating from behind the chair, creating a mysterious and eerie atmosphere. The text on the poster is prominently displayed. The name "Kellar" is written in large, bold, golden letters at the top. Below that, in smaller golden letters, it reads "In His Latest Mystery." On the left side of the poster, in large white letters, is the phrase "Self Decapitation." At the bottom right corner, there is small text indicating the printer and copyright information. The illustration style is reminiscent of early 20th-century lithographic posters, with a focus on dramatic lighting and exaggerated poses. The overall impression is one of mystery, illusion, and theatrical spectacle.
