A second edition was published by the Bilbao Bizkaia Kutxa Fundazioa in 1997. The publication includes introductory essays on the artist's genealogy and biography, and an analysis of the pictorial works. There is a separate section of Documentary Appendices, which contain extensive genealogical tables on the artist's family. The publication also includes an exhibition list, a bibliography, a list of publications where Ucelay's drawings appear, and examples of the artist's signatures.
