Answer Capitals Book, by Vladimir Nikolic, is a free ornamental caps display font with the feel of vintage sign plates and stamped emblems. The letters sit inside repeating cartouche frames with rounded points and a double-rule outline, so the font reads less like plain lettering and more like a set of labeled badges.
It fits poster headers, packaging marks, cafe menus, book covers, and title cards where the framing can do some of the styling work for you. As a free font, it also makes sense for monograms and short cover lines, since each letter arrives with its own built-in border and a neat, old-fashioned label look.
