King and Spadina.
UPDATE (2009-05-26): A new ad on the same wall.

UPDATE: My 3rd book; daily dose of imagery - vol 3 is available now. You can order directly from my blurb page or from my books page. Either way blurb will ship the books directly, the sooner you order the better chance you have to get it in time before end of the year. (you'll notice a small increase in price, and it's because blurb is offering premium paper now which is better and heavier stock.
