It is truly hard to believe what some people spend their time doing, but he really made a beautiful one of a kind model which will be a museum piece. All you can say is "wow."
That's 150 forty-hour weeks, roughly 3 years at a full-time job.
If you value his time at a modest $30 an hour, the model is worth $180,000 in labor alone.
I find it very cool because it seems everything now is mass produced or produced in hurried fashion. There won't be too many valuable objects from this era in the Antiques Roadshow of the future.
