52 Photos Project: the sign says

The challenge this week at 52 Photos Project is: "the sign says".
Well, what does this sign say, a crow on a cross?  
Crows have all sorts of supposed symbolism and meaning.  It ranges from very good to very bad, depending on where you look, but I couldn't find anything specific on the web about a crow on a cross.  There were lots of pictures of crows on crosses though, perhaps implying that at least photographers feel it should be saying something, but I guess we're not exactly sure what.  What do you think it means?
