It's a good thing that I hadn't seen this picture (above) in those days because if I had, I would have been seduced into making really elaborate castles that I wouldn't have wanted to see smashed. Smashing dad's precious castle is just about the most fun thing a kid can do. It could be that a rubber T-Rex smashes it, or a plastic Batman or fighter plane bombs it...there are lots of ways a kid will demolish it, but demolish it they will, probably within 15 minutes after it's built.
Look at that sucker (above)...that guy really put a lot of work into it! He must have been a bachelor!
Here's a nice one (above) that looks a slum dwelling on the edge of one of Dr. Seuss's cities.
Boy, you add color to these things (above) and they look great!
It's a bit off-topic but I couldn't help putting up this picture (above) of a tower built with empty cardboard boxes. If I did this and my kid destroyed it, Armageddon would ensue.
I once saw a built-up paper sculpture of St. Basil's cathedral, for my money one of the most beautiful buildings on the planet. The sculpture was made from one of those craft store books where you cut out a zillion tiny parts and glue them together. I don't know who buys those kits. Only prisoners have the time to make those things, and they're not allowed to have scissors.
