First published in 1887, Gooch's Face to Face with the Mexicans, is on-line here in a very readable format. It includes the many charming illustrations by Isabel V. Waldo, as well as portraits of the characters in my novel, Agustin de Iturbide y Green and his mother, Dona Alicia Green de Iturbide.
Note: an edited (severely abridged) version with an introduction by C.H. Gardiner was published by Southern Illinois University Press in 1966. However, said version does not include the material about the Iturbides.
More anon.
