The mark consists of a black background, depicting a Tyrannosaurus Rex skull, mouth agape, facing right, in the colors white, pink, gray, brown, yellow, red, and outlined in black and green. Overlaying the skull are various graffiti elements in green, white, blue, yellow, red, and black. Also overlaid on the skull are the wording "BLK WKS" in orange and red near the upper jawline of the skull, "esteli" in white near the mandibular joint, "NBK" in white and outlined in blue on the lower jaw of the skull as well as an illegible "20xx" year number in orange outline shaded gray and black directly after the graffiti "NBK". Underneath the entire graphic and slightly offset to the left are large, yellow, stencil-font stylized letters "NBK", below and very small is the phrase "black works studio" in stylized yellow.
The colors red, green, brown, pink, blue, black, white, yellow, orange, and gray are claimed as feature of the mark.
