Srpska Kniga 14, by Nikola Kovanovic, is a free heraldic Cyrillic caps font with the feel of old Serbian bookplates and church emblems. The letters are built like tall shield panels, crowned at the top and flanked by stylized double-headed eagle forms, so the font reads less as plain lettering and more as a set of ceremonial initials.
It suits identity work for cultural institutions, historical exhibitions, Orthodox festival graphics, book covers, and title pages where a free font can carry a strong national and ecclesiastical tone. Use it for short headlines, monograms, chapter openings, or title cards, especially when you want the letters themselves to function like insignia.
