A development from a brief entitled "Collections" in which I used my Grandfather's stamp collection to create a new collection of defaced Machin postage stamps. I invited the public to have a nice doodling session with a choice of a Machin & an abundance of pens. I then uploaded the results to a blog (see below) @ defaceherface.tumblr.com which is open to new submissions.
