Two 35 mm color transparencies of Eugene Garfield (1925–2017) and Huichol artist Emeteria Rios Martinez (-1994). This image was taken in June 1985 at the Institute for Scientific Information (ISI) building located on 34th and Market Street in Philadelphia. While visiting ISI, she participated in "Art Day" where she demonstrated how to create Huichol yarn paintings.

In 1979, Eugene Garfield commissioned a mural for the opening of the ISI building. He later learned that Martinez had received only 5% of the fee paid for the work. In response, Garfield arranged for her to work directly with the institute and provided a monthly stipend so she could create freely. She was also commissioned to produce smaller yarn paintings, which were gifted to ISI clients and visitors.

Over the next two decades, Martinez created murals and yarn paintings that shared the religion, myths, and daily life of the Huichol people.
