Both appear to be duplicates of the original to me .
I use the term original , in the context of this bronze , to mean the actual first model of the bronze box ( a 'proof' , if you will ) , from which molds were manufactured from .
Sometimes the 'original is made from wax and is destroyed in the mold-making process .
The point I'm trying to make is that there's only one true 'original' , when it comes to that definition .
There's many definitions of 'original' , though (original 1949 Ford , etc.) .
There may have been multiple molds made (prob. so) .
I've seen a few multi-duplicated bronze items , alongside of their original (master,proof) .
Most often the original ones are hand-signed ( engraved/carved ) by the artist , and lack certain manufacturers marks (not all the time , however) .
The motif of the lintel on yours is an original stone carved lintel , but there's another stone lintel that's sort of a copy of it (if you get my meaning) .
Nice bronze box , Murena .
How much are they asking for the one on the internet ?
