John Simmonds: Paperweights From Great Britain 1930-2000
Schiffer Book for Collectors 2000
J. S. describes an rare colored sulphide of two ducks.
Has anybody on the board more information's about Paul or Salvadores sulphides from this time?
Or more information of that kind of their paperweights (diameter, high, kind of glass, how is the base like)?
I will send pictures later.
