I know Vigiers pretty well.
Logos were always bold, whether on the peghead or the body, not timid like the bass the Op's has photos of.
I have seen this type (not this very one though) of "inlay" on other less expensive imported instruments.
I't's not an inlay, it's an "overlay"; a paper thin layer of pearl/abalone that is applied on top of a coat of clear finish, then more clear is applied. If you sanded it down to the wood, the pearl logo would disappear.
@kodiakblair; Beautiful instruments my Friend!
