I am wondering if the person who built this, comes from art/craft world not model making. One big difference between our world and the art world, as we tend to network better and tell others what we are doing. I have seen 'models' done by artists , and they are superb, but something in the way they are presented is different. This piece feels like some of those , in particular the cartoon figures and the simple baseboard.
Having said that, I would expect info about the person who built it to be displayed, and possibly contact details , maybe even a website.
