Because no book should be without it's early-60s Puffin edition, even if it was published in 2008. I adapted this from this cover of Little Women, from 1963.
If I were to try t cobble together a legitimate reason for doing this (it took a day! A day!) I guess I was thinking about how much fiction for young women has changed in the last century or so. But basically I'm just a Puffin geek.
