LEGO’s ‘Set for Adults’ just keep getting bigger. This is the brand new 76252 Batcave – Shadow Box, a £345/$399, near-4,000 piece tableau that recreates Batman’s secret lair from the 1992 blockbuster ‘Batman Returns’ in mini-figure scale. And yes, we had to look up what a ‘tableau’ is.

Measuring over half-a-metre in length, featuring seven mini-figures, the Batmobile, and 3,981 pieces, almost all of which are black (or very very dark grey), 76252 is one of the largest mini-figure scale sets that LEGO has ever produced.

Hinging along its right-hand edge, allowing the box – sorry tableau – to open , a variety of small play features are included, which can be controlled from the back via hidden mechanisms. These include a rotating chair, changing computer screen, opening toolbox, and an “illuminated Batsuit vault”. It’s safe to say a ‘tableau’ is more about the visuals than the functions…

Due for release exclusively at LEGO.com on June 8th, the LEGO 76252 Batcave – Shadow Box is – like many of the brand’s recent sets – aimed at ages 18+, although for once the black packaging is more than marketing gimmick. With nearly 4,000 black or very very dark grey pieces, we expect the age on said packaging is more than a marketing gimmick this time too, as we can only imagine how difficult to read the instructions will be.

So what do you think internet? A spectacular homage to the 1992 ‘Batman Returns’ movie, a source of all the black and very very dark grey parts you will ever need, or another unattainable LEGO set priced so far out of reach only Bruce Wayne could afford it? There’s at least a neat circularity to 76252 if it’s the latter.
