The Letter O is noteworthy for so many reasons, be it a nod to son Oliver, daughter Ophelia, or a reminder of that wonderful vacation to Oahu. Our alphabet wall plaques, which look wonderful hung singly or used to spell out ideas, were inspired by vintage typewriter keys. The frames of these decorative elements are made of iron that has been treated to a weathered tin finish. Each letter is sold separately and we offer them in a set of 52 characters that includes the entire A-to-Z alphabet and 26 additional letters based upon popularity.
