A wonderful painterly evocation of the cusp of Spring by Spanish painter Joaquim Vayreda, who painted in the Catalan region in Spain in the late 19th century.
Vayreda was the founder of the Olot school, a painting style focused on that area in the Catalan region and much influenced by the painters of the French Barbizon school.
