About three years ago I visited the Museo Puyrredón in San Isidro and I saw for the first time this painting 'Hortensia Aguirre de Leloir y Marta Leloir de Udaondo' (Óleo sobre tela, Francia, 1914).
I especially like the light and I am sorry my photo doesn't make any justice to this painting.
I was unable to find further details on it online - maybe it is not an important painting, but I like the feeling of calmness it transmitted.
If you want to see it, check out the visiting hours on http://museopueyrredon.org.ar/
Free admission but donations encouraged.
