FELIX BLOMMESTIJN: PLAYING CARD ILLUSTRATIONS
Felix Blommestijn has setup a blog where he's adding a new uniquely illustrated playing card every week. The results so far are really dark and really impressive. Most alternate takes on playing cards seem to stick within a certain set of guidelines, and Felix has also to a certain extent but has also pushed the boundaries by reinterpreting/redefining the individual cards. I think some (if not all) of these are so good they should be elevated to poster/print status. Check the series thus far here.
EDIT: Apologies for the lower quality images, I love having big images on my blog and these were the largest images for the deck I could find (my 2 favourites cards) and these were too good to not post.
