Ninjago City (70620) - Billboard Advertising

I was so wrapped up describing the crab house, ATM, and comic store that I almost forgot to circle back to the billboard outside the elevator structure.

The billboard display is actually designed so that the billboard can easily be replaced, with ads rotated in and out as appropriate. This is absolutely brilliant. I mean, the billboard itself already adds so much vibrancy to the otherwise dull elevator shaft. But now there is the added capability of displaying different ads!

You can see below that the entire billboard sits between 2 rails. The replacement process is very quick and easy - simply slide the current billboard out and replace it with a different one.

There are 4 different billboards that can be displayed. Each with a lot of detail and color.

The billboards that are not in use are stored unobtrusively behind the display. This is such a brilliant use of space with the additional benefit of keeping everything in one place. Bravo Lego! I keep saying this but the thought that has gone into this set is astounding.
