Drawings by Alejandro Sirio (1890–1953).

I first came across Sirio's work in the spring of 2009 in El Museo de Arte
Español Enrique Larreta in Buenos Aires. He received a great deal of praise
in Argentina during his lifetime, but most of his pieces have been scattered
through different collections. In 2007, Ediciones de la Antorcha published
Alejandro Sirio: El Ilustrador Olvidado, but tracking down a copy has proven
to be pretty difficult.

Most online reproductions of his illustrations simply don't do them justice,
but today I came across this incredible Flickr set with 25 large scans.
