This work is one of two works installed on the opposing walls in the Seodaemoon prison cell. It captures the shadow of the window frame, which reflects a window from a high level in the small prison cell. The illusion of the painting, while not actually drawing light, suggests the appearance of light. It is metaphorically showing the truth of the prisoner who is calling the light. Printed photographic images are cut and pasted on a canvas to create contrast with the colored pencil.
