Petronella Oortman's dollhouse was not a children's toy. The estimated costs are around 30,000 guilders. In the 17th century you could buy with this fortune a real canal house on one of the most expensive canals, the so called Herengracht. All objects in the dollhouse are made from the original materials as their real counterpieces, such as wood, tin, silver, porcelain, etc. The miniature porcelain was ordered in China. And Amazon.com was not invented yet. Do you know how long Petronella had to wait before her order from China arrived in the Netherlands? Probably around 1.5 years.
