A number of artists contributed to the success of this project. In addition to Peter Waddell and Philip Alexius de László, who created the paintings of Evalyn Walsh McLean and Friendship Estate, artistic contributions to transform our call boxes were made by Michael Knud Ross, who restored them; Frank Arkwright, who painted them royal blue and hand-gilded the gold leaf designs; little b design, who designed the brass backplates with the historical text for the call boxes; and Gelberg Signs, who fabricated and installed the artwork and backplates.
