 So that Barber could depict Columbus in profile, Curtis arranged for a little-known Washington, D.C. sculptor, Ulric Stonewall Jackson Dunbar, to create a bust based on the painting at the Company's expense; when complete it was forwarded to Barber in Philadelphia.Barber prepared sketches based on the bust on August 15, and presented them to Acting Mint Director Robert E. Preston (Leech was on vacation), who forwarded them to fair authorities in Chicago.Ellsworth showed them to artists working on the exposition, and to the press.
