On what Mexico City monument do these sculptures appear?
¡Buena suerte! Good luck!
UPDATE - Well, I thought this one would take longer than the previous quizzes, but we already have a correct answer.
Joan, a reader who has answered all the previous quizzes, gave a good but incorrect guess by saying the Monument to the Revolution. The sculptures are from the same era, and of similar themes (although those on the Revolution Monument are more stylized.) In fact I was considering using a photo of a sculptural detail from the Revolution Monument for this quiz, but I thought that it would be too easy.

The winner is Gary Denness, the author of "The Mexile", a blog that I frequently visit. He correctly identified these sculptures as being from the Monument to Alvaro Obregón, which is located in Bombilla Park on Insurgentes Avenue in the southern neighborhood of San Angel. Obregón was a general in the Mexican Revolution and the President of Mexico from 1920 to 1924. The monument was constructed in 1936 on the former site of a restaurant where the President was assassinated.
Here is a photo of the park and the monument.
