I noticed Room & Board selling these on their website for $999 ( click here to see.) They have taken them off the wooden dowels and framed them. I have two from the 1950s in their original format: Langoustine & Sea Urchin. Each has some normal wear and tear, but they are absolutely striking.
Created by French physician Dr. Louis Auzoux and drawn by P. Sougy, these rare, collectible plates were used as teaching tools in France from 1900 through the 1960s. Made of chalk paper, these intricate works of art were used by teachers to illustrate the topic of the day.
