vintage brass or bronze w/gilt Baule Ivory Coast style African mask on stand EUC

Description

this is a super cool vintage cast brass or possibly bronze? baule African mask, in great vintage condition.  there are no real issues other than wear that's taken place over time. (please view all pictures to see all parts of the mask).
I am leaning towards brass for the material, but it could possibly be bronze?  I'm sorry I don't know for sure.  it's definitely a solid cast piece & it's quite heavy!  the mask is a beautiful design, and has been painted over with gilt paint in places.  it is on an interesting little stand, also solid cast brass/bronze.  I'm thinking the two pieces were joined together some how, but it's hard to tell.  anyway-it's a very cool collector's piece!  thanks for looking!
