I can’t remember when I bought this puzzle. The last building on the chart dates from 2007, so it’s obviously after then (indeed after 2009, when I returned from Korea). It has three components – a standard cardboard jigsaw of the land (with buildings as at some unspecified earlier time) and water, a foam jigsaw of the land (with buildings generally as at 2007) and plastic buildings which slot into the foam layer. Some details are worrying (like the cricket ground and football stadium being there, and buildings across streets) and some have been superseded (the Entertainment Centre/Convention Centre area (now and Barangaroo). (The manufacturers are 4D Cityscapes Inc, in Markham, Ontario.)
I have done this with my students several times. The foam layer is easier (because it covers less area and has larger pieces) and more interesting. The cardboard layer is much harder. We did this in the last class of last year, and completed about 3/4 of it. Getting it home was a challenge, but I set it up on the dining room table and continued occasionally for almost two months.
I finished yesterday. This person finished quicker, and included stirring music.
