This is a Mobaco construction toy example, created by a Dutch factory Moubal from 1920’s to 1950’s. Mobaco consists of wooden pillars and card board plates, which allows for different structures. This setup was already used as drawn picture on front side of manuals & advertisments. Even before some specific parts were sold. Building this city, will require many large Mobaco boxes. The Mobaco library is also released (LDraw format), so you could build yourselves. For more information, see [website](https://retrobuildingtoys.nl/category/vintage_toys/vintage-toys-collection/).
