OK, So now you've seen that there is no more over-the-top wooden toy in the whole lot than "Hamburger Hafen", a 500-piece replica of the port of Hamburg by the graphic artist, designer and professor Alfred Mahlau.
If Ladislav Sutnar was never able to get his "Factory Town" block set into production--which had 15 pieces in the whole thing--imagine manufacturers' reactions when Mahlau pitched them a construction set with 15 wooden oil storage tanks alone. It's like Playmobil out of wood. Crazy, but genius.
