If it were late 1920's Murano, it would be Martinuzzi for Venini, as that's when Martinuzzi developed pulegoso. To me, it's too simple for Martinuzzi and the surface isn't rough enough. I'd be very happy if it were Venini, not just because I like to see Anita happy, but, well, snap, I've got a very similar piece, same finish on lip and same pontil mark.
