Hello Collector245, the set comes already assembled, no box, no instructions. As Wout suggests, if Lego masterbuilder made several of them, where are they? I searched on internet a lot and I found only those two pictures of the original Lego Idea book.
Here, we go, this is the massive set I found! 50 years and still going strong!
The set is...big!!! And heavy, increadibly heavy. As far as I know this could be the biggest massive set that Lego manifacturers did so far. Hope this could be interesting for those also that are interested in Lego Apollo recent sets, the details are lower here but vintage style is fascinating! And the size is..wow! The view is also flipped with respect to that of the published picture, enjoy! Any other information about other existing dioramas like this would be very appreciated, thanks!
