These are two seperate pieces done on pages of a book.
I bought a German book with the play 'Leonce and Lena' and a piece called 'Lenz' by Georg Buchner for 99p from a charity shop. I am using it as a sketchbook, the idea being the written text comes through slightly the paint.
No reason for butterflies really, I just doodled.
Tipex and biro.
