In response to images we posted Friday of Transamerica sidekick, the residential twisty cylinder (not that you can see them at the moment), reader Bennett Hall sent us a nice triptych of the construction of the original pyramid. Awww... it totally brings us back. To that time we watched Zodiac. Bennett has more historic photographs of San Francisco over at his blog, San Francisco Images.
