Sorry for coming in so late on this - that's just me.
If you are still interested, here are some pointers. Pirelli made statuettes (as they called them) in clear soda glass for about the first ten years of operation, almost always with coloured eyes, ears and tail and often a coloured nose. It isn't true that all Pirelli figures have eyes with two colours, but most do. The boxer dog was not included in the 1959 catalogue. It is a later addition and is usually a sitting figure in brown glass with white paws and a red tongue. Scavo's boxer dog doesn't have the coloured ears nor tail. Its a lovely piece but not, I think, Pirelli.
