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 wood engravings we have were available for sale at the PPIE and many were the actual prints exhibited and have the label from the PPIE.
The painting, "Portrait of a Young Girl" by Velazquez, was done between 1638-1644, and resides in the painting collection of the Hispanic Society of America Museum in New York. The identity of the young girl is unknown, though it is suspected that she might have been the artist's granddaughter. It's considered one of the finest works of the 17th-century naturalist period and one of Velazquez's most recognizable.
