Karla Lessa participated in the “operation” of transferring the negatives of sculptures at the Louvre Museum (only in Brazil are there negatives of the sculptures at the Louvre) in order to enable the renovation of the place where they were kept. As a student of the Sculpture Course, she did not allow laypeople to make the “change” the way they intended, as she knew that the plaster of 1816 (had been brought by the French Mission) would not withstand sudden movements. In this way, it prevented irreparable damage to the material and, consequently, to the history of art. The transfer was carried out correctly and accompanied by a competent restorer. These sculptures, on the positive side, are now on display at the Museum of Fine Arts.
