Here are a few of my favorite extinct typefaces. These are creations of the 19th century, though some more modern faces have become extinct, too.
One of my favorites is Freak, recently produced by Sky Shipley of Skyline Type Foundry http://skylinetype.com. This wildly eccentric 1889 gem is pictured below.
Yes, fonts are fun, and especially if you’re using one that very few people commonly see. Using extinct typefaces is a big perk of letterpress printing. It’s great to be able to share them with the world!
