Art purchase - Paul Madonna pen & ink drawing

I attended SFMOMA's Artist Gallery sale last night and hoped to find something inspiring. I made a great impulsive purchase a few years ago with a Winni Wintermeyer photograph "280". I've really grown to love that piece. Well, I did find something. It's a Paul Madonna pen & ink drawing of SF from his weekly SFGate series All over coffee. I love his moody and melancholic mixture of "overheard" text with gorgeous SF urban drawings. His work is direct pen on paper, with no pre-sketching, so there is a "mistakes and all" beauty to the drawings. This piece called "On Guerrero" was published 10/25/09. I was also attracted to it b/c the words capture alot of what I was feeling last year. 2009 was a brutal year.
