Now this is marketing. The nice folks at World Label bring us a collection of vintage-style apothecary labels. The sheet is a customizable PDF file, so you can add text using any font on your computer.
Here's an example of the labels in use. They're obviously aimed at the Martha Stewart crowd, but would be equally at home adorning all sorts of prop specimens and preparations.
This is another good example of how those of us with a darker bent can plunder the tools and techniques of home crafters. Odds are that I'll never decorate my bathroom with faux-Parisian toilet water bottles, but the exact same approach will produce some cool period storage bottles for a vampire hunting kit.
