The Letters are individual Paintings. They are around 15"T x 13"W x 4"D and are usually mounted on 24" x 24" plexiglass for hanging. The letters are made out of aluminum with a lacquer color and metallic clear coat. My Paintings evolve around the shape of the letter and what it says to me. The "D & R" were designed as combo for a lovely married couple, they have been sold. The rest of the letters are for sale. Please contact me for pricing.
