To clearly state why it is that Rusty paints on glass just in case it is illegible in the above images...
" Like most Psychometric Impressionists, Rusty prefers to work on glass so he can keep in constant touch with the object and allow the essence of its 'significant past' to pervade his sensibilities as he paints."
Just got this book in the mail and I am very entertained. There are other painting cats included in the book and a history of cat painting that is first recorded in Egyptian times.
