Dr. Paul Pfurtscheller produced a series of zoological wall charts, now considered among the finest ever made. I own his chart of the mussel, circa 1910, and it pains me to look at the damage. The patina of age and use for 100 years includes soil, water stains, paper loss, cracks, fold lines and one rod is missing. *Sigh* the duct tape is the worst though.
The conservator shook his head like a doctor when things look bad. Could I possibly mount this on an armoire or cabinet in an interesting way?
