The art director for Vintage and Anchor Books invited a bunch of folks to design covers for Nabokov books in specimen boxes (the kind that might be used to display butterflies). Above is Stephen Doyle's creation for my favorite Nabokov novel.
I also like this one by Chip Kidd because it evokes the structure of Nabokov's longest (at 600+ pages) novel, whose five sections get progressively shorter.
This [blog] is my Savings Bank. I grow richer because I have somewhere to deposit my earnings; and fractions are worth more to me because corresponding fractions are waiting here that shall be made integers by their addition. —Emerson, Journal (1834)
