The Urban Sketchers blog, which I first wrote about in 2008,
just marked its 5th anniversary (the corresponding Flickr group is about a year older).
There are sketches from contributors around the world to this blog, the tagline of which is: “See the world one drawing at a time”.
In addition to pencils, pens, markers and other typical drawing instruments, many of the sketches are done in watercolor, or pen and watercolor.
I particularly enjoy those occasional photos in which the sketch is shown in the context of the subject, not only because it’s interesting to see the scene being interpreted, but because you get a much better sense of the scale of a drawing than you do as an isolated image on a web page.
