When you read an advertisement for a sale that promises Swanky Swigs, you know there are several possibilities. One, the person could be one of those people who calls every vintage glass a Swanky Swig, and we all know what we think of them. Two, the person could be one of those people who knows exactly what a Swanky Swig is and is not going to be selling them cheap.
Or - and this is an unlikely possibility - the person knows exactly what a Swanky Swig is, but the person is moving and is more than happy to make a deal with someone who's willing to take them all. Here's a really unlikely scenario: The person will have not only a nice array of Swanky Swigs, but two of the tall 1937 Tulip #1s, which we all know are really hard to find. Because in all of your years of Swig hunting, you've found only one of them.
I'm not suggesting this kind of thing happens often. When it does, it's a pretty good day.
