Yesterday we visited the Picasso Museum in Barcelona. The museum contains his early artwork from age 13-19 and his much later in life artwork.
I enjoyed seeing his ink drawings and his early artwork. He was a mastercraftsman painter at age 15! The collection contained many studies he did before he completed his finished paintings. He planned and tried out several different ideas, compositions and techniques before he produced his finished painting. So you could say that Picasso did his homework.
