The “Vision after the Sermon” is an
oil on canvas painting by French artist Paul Gauguin, painted in 1888. It is obvious that

It depends on the flags they are painting if they are painting the United States flag then its a symbol of freedom and liberty. When painting flags it can have different meanings and symbols for their artworks.
