Yes, I did too- there was a theme park site that was swallowed up by rollercoaster.com, but the theme park site had beautiful old photos of six flags over texas, including construction photos and conception artwork for the different areas of the park.
I've found a few brochures, including the beautiful 1976 brochure - the artwork is magnificent!
I remember getting the brochure at my local TG&Y in Oklahoma in March of 1976, thinking how excellent it was. The artwork sure inspired my imagination, much more than the later ones with photos did. I also found the 1978, 1979, and 1980 brochures and am in the process of scanning them.
How do I post them here?

Louis
