Three Heads Aged Version

This is a version of my black and white ink pen drawing 'Three Heads' which can be seen here: [link]
I wanted to see what the drawing would look with a tea-aged background like some of my other drawings. But I didn't want to touch the original! So I made the paper, and then printed the scan of the original drawing onto the paper.
(This piece is therefore way bigger than the original - nearly a whole A4 sheet where the original is a tiny drawing. (10.5x12.5cm)
