Since 1976 he works at the Guayasamin Foundation as a leading executive due to his family ties to Oswaldo Guayasamín (Vera Arrata is married to his daughter Saskia).
In 1972 he replaced Oswaldo Guayasamín as the President of the House of Ecuadorian Culture, after Guayasamín had a disagreement with General Vicente Anda Aguirre, the minister of education during the dictatorship of Guillermo Rodríguez Lara (in office: 1972–1976).
The artist's last exhibits were inaugurated by him personally in the Luxembourg Palace in Paris, and in the Palais de Glace in Buenos Aires in 1995.
