Wikipedia defines a moustache (UK /məˈstɑːʃ/; American English: mustache, /ˈmʌstæʃ/) is facial hair grown on the upper lip. Moustaches can be groomed by trimming and styling with a type of pomade called moustache wax.
A typestache on the other hand, is styled by a typographer. These curly brackets have been selected for display and labeled by designer Tor Weeks. The brackets look remarkably like their namesake, the Typestache.
From designer Tor Weeks: Typestaches actually started as a wine and cheese party invitation design. Halfway through designing said invitation, I started playing with brackets as accents pieces. It was when I was attempting to choose the right typeface for the design that I had a whole selection of brackets on the page so from there it just took on a life of its own. All I did was have the good sense to stop forcing it to be an invitation and let it be a poster.
This poster captures the perfect balance of quirkiness, whimsy, and simple clean typography– titled A Field Guide to Typestaches, it shows you how each typeface’s definite brackets can be turned into distinctive moustaches, when you turn them on their sides. The best part of all this is the little moniker labeling the typestaches, which personifies each type as a gentleman of sorts.
While the original poster is no longer available, version 2, in gold on black is available here.
