According to W. Roberts in his 1917 catalogue of the John H. McFadden Collection, the original miniature oil painting for this portrait was destroyed in a fire. No further details - such as the date or the exact identity of the sitter - were given.
In 1915, the year before his death, the American wood engraver Henry Wolf won the Grand Prize for his printmaking at the Panama Pacific International Exposition (PPIE) in San Francisco. The Wolf prints we have were available for sale at the PPIE and many, such as this, were the actual prints exhibited and have the label from the PPIE, with his return address and the edition size and original price of $18.00 noted.
