Furthermore the image used is one that compresses uncommonly well with PNG (small palette, large chunks of solid color). I think the vast majority of 350x400 images would be at least 10x larger unless they're deliberately composed in a similar style or are JPEGs with the quality turned way down. I tried to create an SVG version to see how an SVGZ would compare, but evidently I'm too crap at Inkscape and kept screwing it up.
