If you collect Simpson planets, then THIS is one of those that you want. The hardcore Simpson collectors know that the best planets to get are actually those that are unsigned. That's because we know that these marbles are both early - created in the 80's or very early 90's - and they were most likely made by Simpson's hands himself, before Josh became uber-famous and hired a huge team of glassblowers to help him with the demand for his work. On top of that, I find that these early planets are the most interesting planets also, with neat land masses and fascinating things happening in the glass. This inhabited planet is seriously cool, with wonderful details in the land areas, and a very cool satellite with a bubble trail following behind it from its planetary base. It's got a couple of sweet volcanoes also! All around, a fantastic example of an early Inhabited Planet!!
