Book themed Tshirt idea

I've always been really big into art and have made lots of hand painted tshirts.

What I've been thinking I want to do lately is make some book themed tshirts. My questions are these...
*If I was to make these tshirts/tote bags/what ever else, would anyone be interested in buying one?
*How much would you be willing to spend on it?
*What books would you like to see have tshirts/tote bags?

I'm thinking about taking small quotes from books, themes, team whoevers, or even just the names of the books.

I'm also thinking of doing shirts for blog names.
