The 1960 Vintage paperback edition of Vladimir Nabokov’s The Song of Igor’s Campaign is missing its cover. I’ve uploaded a scan of the cover from my copy, as well as a scan of the indicia page to verify that this is the 1960 Vintage edition; and a scan of the final numbered page to show that it is page 135. I’ve also uploaded a scan of the back cover in case the proto-ISBN there (394-70718-4) is useful. I cannot find a matching copy on Amazon, even using an ISBN of 0394707184.
