HOUSTON --Astroworld was part of Houston's rich history, and it seems everyone has a memory of the amusement park. It's now just a field of grass, but it will soon inspire a new generation of Houstonians. The original model of Astroworld was built in 1968 by Ed Hendersen. Since the dismantling of Astroworld, an 8 foot by 10 foot model has been sitting in pieces in Hendersen's garage. Last year it was put back together and put on display at a local gallery. Instead of taking it apart after the exhibit, they decided to sell it on Craig's List. Well, it sold Thursday for $3,000. The buyer is the engineering firm that did the original work on Astroworld. It is donating the model to the Houston Public Library, where it will be put on display in a reading room of the newly renovated Julia Ideson building in downtown.
