A couple of weeks ago I stumbled on the British website Good Show, Sir! which collects - parades might be a more appropriate word - the most laughable examples of science fiction and fantasy book cover art. Unicorns, cat people, bare-breasted ladies... and centaurs... seem to be among the most frequent visual elements on display there.
I took a look over my shelves to see which book covers I could offer to the site, and came up with an awful Bradbury cover, plus a few others. Little did I know that the 1969 British Corgi paperback edition of I Sing the Body Electric! would end up being the highest rated cover on the whole site.
Click here to see the cover, and the witty responses it garnered from the site's visitors.
I also posted this Harlan Ellison cover, which prompted a response from Mr Ellison himself.
