Focusing on the Timeline of The Blue Guitar, discuss the Autumn 1976 – March 1977 about the 1976.
Autumn 1976 – March 1977 After a series of ink drawings, Hockney draws the twenty etchings in London, collaborating with friend and master printmaker Maurice Payne at Petersburg Press.  
Stevens's meditation on Picasso's painting The Old Guitarist (1903–04), leads Hockney to paint additional reflections in his London painting studio, resulting in Model with Unfinished Self Portrait (1977) which shows Gregory Evans lying asleep in front of painting Self Portrait with Blue Guitar (1977), oil on canvas.
"My self portrait, which was not finished at the time, was leaning against the wall of my London studio. Gregory posed on a bed in front of it and a great deal of his figure was painted from life. That gave it a kind of power. It looks as though it's a painting of two completely different kinds of space. It seems as if there's a stage behind Gregory with a curtain. The curtain has been pulled back and there I am, about to draw a guitar." — David Hockney
