I'll be the first to admit it: I don't "get" the Las Vegas concept. It promotes several debilitating vices, it's overflowing with one of my least favorite creatures on earth (human beings) and it's a model for knocking down cool old shit to make way for ugly new shit. About the only thing I want to do there is fly in, grab a rental car and drive the hell out of town, preferably to some any of the beautiful wilderness one state over. Oh, and that's another thing: its very hideous presence means there's necessarily that much less beautiful wilderness on the planet. But you could say the same about any city, so I can't really deduct points on that count.
I do like visitors, however, and if it's one thing people can't get enough of, it's classic Las Vegas. The number of sites dedicated to preserving the memory of the magnificent edifice that was once Sin City is truly overwhelming. You'd be surprised at how many folks stop by Bostworld just to look at the pictures of old Las Vegas menus that I inherited from my grandfather. As it turns out, my other grandfather liked to visit Vegas too. Though he wasn't as drawn to the promise of disgusting "fine dining," he did enjoy collecting postcards.
I suppose it would be stating the obvious to say that most of the landmarks depicted on these cards are long gone. If I spent more time in Las Vegas, I might be able to tell you if any of them are still standing. Fortunately, the tonnage of Vegas ephemera in the net includes historical maps. You can also find a serious slewful of postcards like mine on Flickr, including many that are, for all practical purposes, identical to mine. But since excess appears to be the hallmark of The Strip, I say the more the merrier.
