The masterpiece

A poster that I saw on one of the busy junctions:

The Hebrew captions say:
(Avigdor) Lieberman
(is) the "puddle" of
the Russian mafia.
(He is) Selling out Israel.

Mikhail (Michael) Chernoy (beside the photo)

I would really like to know who is the author of this masterpiece.
Unfortunately, he or she didn't bother to sign his or hers name on it.
