Two simple but effective sci fi-horror posters from the 1950s. I think the Donovan's Brain (1953) one is really threatening. Attack of the Killer Shrews (1959) is another example of 'nice poster, shame about the film'. To be fair, the movie takes itself seriously but can't escape its low, low budget or the fact that the gaint shrews are terriers in rugs over their backs with tails attached. But that poster would make me want to go and see it and is years ahead of its time in its bold, bloody premise and arch, pithy catchline.
