Sorry about the typo - thought I'd changed that already. #21 is a new version of #11 without the typo. #22 & #23 have a different image and an alternative purple with black instead of grey, and changes to the fonts.
Moved #23 into the not-interested column only for organizing purposes. We like the caricature and fonts, the caricature in 23 seemed to make Dr. Eliot have a larger face (the line continuing with the direction of the book was creative, but we're not sure it's right for the logo. Thanks for putting that out there though!)
