these beautiful charcoal drawings just came in. they are huge. the owner took them to a framer who sprayed some kind of a fixative on them, and the fixative turned white, as you can see in the detail. our job is to reverse that effect much as possible, and reintegrate the areas as best we can using charcoal...both tricky tasks. but we've had some interesting problems like this come through the lab lately, and are happy for the new problem solving challenges.
