Book cover(s) of the week

Decided to post a double whammy today as I haven't done one of these posts for a while. Here's two classic orange sci-fi books by John Wyndham. The Kraken Wakes is illustrated with a more bold heavy black, decidedly b-movie feel, while The Day Of The Triffids is slightly more playful and cartoonesque with overlapping colours and the triffids appear less menacing on this cover, like giant friendly thistles.
