From the new to the old

After just posting Tony Sava's masterpiece, the most recent large cathedral incorporating all kinds of modern building techniques, let's turn to one of the oldest large cathedral MOCs. Diepuppenstubensam has been posting old LEGO advertisements, including this Cologne Cathedral from a 1959 ad in Das Spielzeug, or The Toy, a toy industry magazine. The text says that this construction proves the quality and precision (presumably of LEGO as a building toy). Realize that this is back when only basic bricks, plates and slopes were available.
