Do You Remember When Santa Claus, Superman, Captain America, and Ronald McDonald "Liberated" Bulgaria?

Of course you don't. Because it wasn't American pop culture figures who did that. It was Soviet soldiers who overthrew Bulgaria's ruling government. In fact, there was a statue erected to this historical event in the Bulgarian capital of Sofia. Recently this statue was "vandalized" but an unknown individual or group. I think the definition of "vandalized" may be "greatly improved." Check it out:

Depicted, from left to right: The Mask, The Joker, Wolverine, Santa Claus, Superman, Ronald McDonald, Captain America, Robin, and Wonder Woman. 

Apparently this all happened in one night. This group is obviously artistically talent and nothing short of sheer genius. Just seeing Santa and Superman carrying guns makes the whole thing worth it. And how does Robin make an appearance but not Batman? 

What was the artist(s) trying to say? "In step with the times," said a cryptic message below the painted statues. Times, indeed...
