Note: Slight differences are inevitable between replicas due to deterioration of the mold or to variations in the finishing of the wax or chasing of the bronze. With regard to modern bronze production, a replica may refer specifically to a cast made by someone other than the artist, but who is under license to make the cast. An ‘artist’s replica’ is a cast made by the artist or someone sanctioned by the artist. An ‘authenticated replica’ is certified as having been made by the artist or someone sanctioned by the artist (Tate Papers No.8 https://www.tate.org.uk/research/publications/tate-papers/08/terminology-for-further-expansion).
Note: A ‘copy’ is understood here to refer to a cast that reproduces the features of a model or bronze, but is not created by the original artist of the model or bronze, or cast by a licensed or sanctioned foundry.
