I hit my first Austin estate sale in a while. It was on a Thursday and Friday, which led me to believe that it wouldn't be fully picked over by the time I got there. And it wasn't; there was a great kitchen table and a few other pieces left.
One of the smaller pieces left was a mid-century kid's microscope set. I had to pick it up for the kid in hopes of a happy atomic future. Also, the design of the case (with the old school Steel logo) and the materials inside was worth the cost of purchase.
