I found this great blogsite of an exclusive group of artists from all around the world, uploading their very own "location drawings" to create an online compilation of a drawing gallery plus a treasure trove of fascinating tales about the story behind them.

Their manifesto:

1. We draw on location, indoors or out, capturing what we see from direct observation. 2. Our drawings tell the story of our surroundings, the places we live and where we travel. 3. Our drawings are a record of time and place. 4. We are truthful to the scenes we witness. 5. We use any kind of media and cherish our individual styles. 6. We support each other and draw together. 7. We share our drawings online. 8. We show the world, one drawing at a time

Pretty neat huh? Here are some great examples of illustrations from the site.

You can be featured as an urban sketcher as well, just submit your drawings to the site admin (details of how are found on the blog sidebar). Check out the site here.
