A debut novel by Nancy Grossman has a beautiful cover featuring butterflies in a mason jar.
Again with the butterflies! Not that I am complaining about any of these covers, or about mason jars or butterflies, I just find it interesting that these images seem to have such a universal symbolism. Butterflies represent nature, and beauty, and freedom, whereas another creature, say a squirrel or some other thing that is relatively benign, provoke mixed responses from people.
Perhaps this post is pointless- I am sure I didn't blow anyone's mind with any of these thoughts- but I always enjoy a good cover mash-up.
