I've seen two different types of metal statues. Some have the same size base (including the players name). Face details are slightly less defined. Sometimes these are listed as prototypes, but they could have been produced after the fact.
The other type has a much thinner base (without player names). The ones I have are all painted. I have no idea of their origin.
