What's with the popes? It's nothing personal.

I was looking for a new subject for a series of blind contour drawings (last year, I drew Friedrich der Grosse once per day for a month). I really like drawing old men - the wrinkles are great fun. I thought to myself, where could I find some wrinkly old men to draw? The answer was obvious.

So: one pope per day, in order. Each drawing starts as a blind contour (a continuous line, without looking down at the paper), and then embellished. Let's get drawing!
