Image Rescue Plaques

In April 2014 I began to photograph stainless steel plates that were mounted on large-scale graffitis. I prepared a drawing expressing my opinion that
  1. they had to do with selected parts of the graffiti that were particularly beautiful, e.g., those parts made with a stencil
  2. that they were covered with the plate to conserve them - let's say for 20 years.
  3. that the plates would be removed after 20 years and the graffiti detail would be confronted with the prevailing circumstances and what had happened in that time.
