hello buysel - having looked thru Gulliver, don't see this exactly, but then that wud be too easy. Can only assume your lighting has accentuated the pink - it looks bit brighter than those in the book. I assume you have some base wear comensurate with a Victorian piece. For what its worth can also say that Gullivery felt thes bi-coloured stylised Acanthus leaf pieces of sufficient significance to devote a two page spread to the subject i.e. pink/white - green/yellow also amber/green/pale ruby.
However, for some reason he avoids giving any attribution. Manley gives a couple of examples with bi-coloured leaves, which he quotes as Stevens and Williams, and dating to about 1890 - 1900. Can you comment on any ovbious wear. cheers Paul S.
