According to poet and designer Robert Bringhurst, "Typography is the craft of endowing human language with a durable visual form."

From the storied Helvetica to the downright ridiculed Comic Sans, typefaces imbue the written word with an aesthetic personality. A stern statement is rendered that much more serious under the guise of Times New Roman, while a friendly missive is softened even more by the touch of Georgia Italic. Fonts have, for centuries, transformed the way we communicate on paper... and now online.

The world of digital typography is full of experimental fonts--available for free online--but the realm is also rich in homages, those designs that pay tribute to everything from the architecture, art, music and pop culture of yesteryear. We've scoured the web to find some of our favorite retro-inspired imaginings. Behold, 15 free fonts that harken back to vintage typography:

2. Genplan

This font is inspired by Soviet typefaces of 1930's. We have Dmitry Goloub, Russian graphic designer, to thank for the cyrillic wonder.

3. Alt Retro

The name says it all. This particular font comes from Cyprus-based Andreas Leonidou.

4. GRN Burgy

From one Oklahoman (designer Chris Skillern) to us all: "I hail from Tulsa, Oklahoma, a city that flourished in the early 20th century due to the discovery of oil. Because of the period it was born into, Tulsa's downtown is filled with beautiful art deco architecture. This font is a tribute to my city, inspired by the tall, condensed lettering of art deco-style posters."
