About this card
The central head rears back toward the upper right, putting the white fangs and pink interior of the open jaw near the middle of the picture. Red and black are the only colors in the background, and a yellow line traces the body so the shape does not sink into that dark palette. The two arm heads point in different directions, and all three heads reach the edges of the frame.
