Ballymun RO Bold, from Ronald B. Ogawa, is a free sans serif font with a friendly late-1990s display feel. The letters mix sturdy vertical strokes with soft, rounded shaping, and the single-story lowercase and curling y give it an easy, informal rhythm instead of a neutral corporate tone.
That makes this free font a natural fit for posters, shop signs, CD or book covers, logo sketches, and short headline work where you want plain forms with a bit of bounce. It also suits title cards and large pull quotes, because those rounded bowls and simple tall letters keep the word shape direct while the hooked y adds a small memorable twist.
Ballymun is a san serif font created by Ronald B. Ogawa in the spirit of Brinkhurst's statement that one could "write a humanist letter and leave the serif off."
It contains the Unified Canadian Aboriginal Syllabics as well as the WGL4 character sets.
