Friedrich Richard Petri (1824-1857)
A painter born in Dresden, Saxony who eventually settled in New Braunfels, Petri was known in Texas for his sensitive portraits and scenes of pioneer life in the Texas Hill Country. He became well known for painting portraits of the local Indians who were then serving as guides, interpreters, and scouts at Fort Martin Scott. This sketch had moisture damage and was yellowed, stained, distorted and molded.
Carrabba Conservation began treatment by washing the work. Then gentle chemical treatment was used to reduce the yellowing and stains, and to stabilize the mold growth. The paper was humidified and finally flattened, achieving a much-improved appearance.
