Lisa Krell, our art teacher, drew these three pictures in 2002. The eagle and the old building were rendered in pencil, but the frog was produced with pen. In these pictures one can see that, even though they are all monochromatic, there is a distinct difference in style from the pencil drawings to the pen drawing. This is achieved by using different shading methods, but using a different medium will also change the style even though it is still black and white.
