A very kind man from Montevideo named Emilio Irigoyen posted a link about this in the comments area of this website last year and I have just now seen it.
Very exciting to know that in honor of the 150th Anniversary of his birth, the government of Uruguay has finally posted an official plaque recognizing the birthplace of Jules Laforgue in Montevideo. It is so wonderful to hear this — I wish it had been there back in February 2010 when I made my pilgrimage to Montevideo in search of his birthplace. The building had been torn down so I had to kind of guess where it was. Anyway, here is a link with more info!
