Together with a fellow collector I am working on an article on Chinese lampwork and millefiori paperweights, and I am trying to get evidence for when particular designs were made or marketed, particularly pre-1960. This might come, for example, from early auction catalogues, books, or sales brochures with images. Evangeline Bergstrom had a few early Chinese paperweights, and gives images of these and dates of acquisition in the late 1930s. But there may well be more information like that somewhere out there. Any help gratefully received.
