there are different figures by Livio Seguso for Gralglas. I remember a fish, a seal
and chunky elephants in at least two sizes and I´ve seen others, but can´t recall what
They pop up now and then on ebay.de; have you tried searching for ended listings?
Being signed with the monogram LV seems to be the standard, but I recall a piece with
a full signature recently.
