No good idea goes un-nicked.
A couple of years back, the first poster below, by Sean Hartter, popped up online as part of an ongoing series of spoof-retro movie posters. Today, an exact lift of the idea – sort of a what-if-Hammer-Studios made Ghostbusters poster – appeared online (seen below). One expects it`s someone that felt they could do better than Sean (and depending on your tastes, perhaps they did), but it`s hard to credit them without knowing where it came from. But at least we can give another nod to Sean.
