TOOLS of the TRADE:
book covers
I came across a really cool site dedicated to book cover design called covers.fwis.com. I personally find book cover design interesting because you have to entice the customer from feet away. I like the lettering styles on the covers that I pulled from the site.
It's maintained by Fwis, a design firm based out of Brooklyn, NY and Portland, OR. They specialize in fresh, concept-driven graphic design. There are some wonderful graphic design and inspiration to see on their site.
