Martha Stewart uses custom type.

It seems the slab serif font is called "Archer" and the serif font is "Surveyor" both created by Tobias Frere-Jones (http://www.typography.com/) for Barbara de Wilde, the former art director of Martha Stewart Living. Surveyor (which must be the italics on this cover) is based on old map fonts. See this article.

I couldn't find font showings for either, though. Maybe now that Martha's a bit hard up she'll sell these fonts to us peons to raise some cash.

Don't you think Martha will look stylish in pinstripes? Its a good thing

I for one like the all-orange prison wear, but that might be too street for Martha.

My first job was working for her (then) husband, 20 years ago. She wasn't nice to me. I can't feel too sorry for her.
