Contest: A series of 20 The LEGO Batman Movie characters to win!

Let's go to a quick little contest that will allow one of you to win a full set of 20 characters (ref. 71020) from The LEGO Batman Movie.

Let me tell you the story: LEGO mistakenly sent me, like many other sites, a complete box of this series of minifigs when I shipped the box of series 18 minifigs intended for use. of a test on Hoth Bricks.
Rather than returning it, LEGO offered to keep this box which contains three complete sets, without giving any specific instructions regarding its use.

Since I don't keep ANYTHING from what LEGO sends me, I have already put into play two complete sets on social media in the last few weeks and I now put the last set on the blog into play.

Please note, the duration of the competition has been intentionally shortened to try to reserve the operation for regulars of the site.

It's your turn.

A complete set of The LEGO Batman Movie minifigs to be won!
