Production of classic paperweights in 19th Century America, only got underway in the early 1850s, a few years after they had become "fashionable" in Europe.  Initially, the designs tended to copy imported styles.  However within a few years, Boston & Sandwich (B&S), the New England Glass Co. (NEGC) - and during the 1860s - Gillinder, were creating some fine, highly-collectable weights. The rare - and highly sought after - paperweights attributed to the Mount Washington Glass Works are believed to have been produced in the 1880s/90s
