Ha! That is an awesome example for sure. How much does a clear one run? I know nothing about them, but my wife is a scientist and her name is Lindsey spelled the same way so I thought it would be cool to get her one.
There are a lot of different versions made over many years so the values vary widely. The common ones may go for $40-50 with the high end rare ones being about $3000, many in between, take your pick.
Last one I bought was at Adamstown PA. A nice early aqua Pittsburgh one for $75
