Rare PY-Signed Thistle

A rare purple & green millefiori thistle on a translucent mottled amethyst ground with the PY signature cane set near the end of the stalk.
Although not in keeping with the artist’s usual practice, this weight was finished with a polished, concave base. Dark tint to the glass; probably pre-1940 Moncrieff period.
(See Colin Mahoney’s book “Masterworks: the Paperweights of Paul Ysart”, page 116, for an almost identical example).
