A LEGO exhibition in Levallois from December 14 to 29

If you are in the Paris region, here is an appointment to note on your tablets: The city of Levallois is organizing a LEGO exhibition from December 14 to 29, 2013.

The event will take place in the halls of honor of the town hall. On the program, a Christmas village and a 100% LEGO city.

I don't know if these are MOCs offered by one or more LUGs or official LEGO products presented in the form of a giant advertisement for the Store next to the SO West shopping center. 

The site of the city of Levallois indicates in its presentation that "The LEGO Ambassadors will offer to join the big family of LEGO fans!".

It's not very clear: Are they LEGO employees, town hall employees dressed as LEGO employees or volunteer AFOLs who will present their creations?

If you know more about it, don't hesitate to mention it in the comments.

The exhibition will be open every day from 10 a.m. to 00 p.m. and on Thursday until 18 p.m. Free entry, it's free.
