I have come to believe it was about 1985 that I started to seriously buy some LEGO. The Basic Brick set 350 had come that year and I got 8 of them for about 12 bucks each. That gave me a nice start on some bulk. I started small, mostly just noodling around. It's the stuff you wouldn't take pictures of, and there wasn't anywhere to put stuff like that. I did take a a roll of 35 millimeter film and printed those pics. This is them, scanned, slightly cropped, with the brightness, color and contrast tweeked a bit.
I started making buildings first, then it grew into a statement about uncontrolled building. In the world of those small plastic buildings the right to the air space above buildings gets sold and they build in it. The buildings don't have much detail, especially compared to the Micropolis type building, but that wasn't the point. I certainly didn't have much gray back in those days. It just wasn't as common as it is currently.
It's kind of hard to see everything. The pics just aren't well enough lit and it's a pretty big lump of plastic. It was about 2 feet deep, 30 plus inches wide and more than 2 feet tall. The smallest buildings are supposed to be 3-5 story buildings, then bigger ones are built over them, finally the giant upside down U-shaped building gets tossed up. You can see more pics at Flickr.
