Why on Earth would I put banner ads in my  book?  
Because brands still want them. And agencies still create them. And honestly? I enjoy the monotony of producing them. Swiftly building every layer, every frame. Ensuring consistency. Examining each percentage value in each color swatch. Following style guides. Labeling all layers so the developer doesn’t go mad. I’ve slayed thousands of banner ads, and I’m not afraid to say it loud and proud.
