The bat symbol on the chest has also alternated from a simple black bat, to a bat design on a yellow ellipse, lending a logo-like appearance more akin to Superman's "S"-in-shield logo. The yellow ellipse was introduced in 1964 as part of the "New Look" Batman stories. In "", the yellow ellipse design was explained as being a heavily armored, intentional target, to draw enemy fire away from his unarmored head and body. A subsequent issue of "Shadow of the Bat" re-established the concept. The yellow ellipse was eventually removed in 2000 after a 36-year run and replaced by a large stylized black bat-emblem, which resembles the one from the Golden Age comics.
