The New Bremen Glass Manufactory, on the banks of the Monocacy River near Frederick, Maryland, created glassware that reflects earlier German counterparts. This tumbler bears floral engraving seen on other pieces attributed to John Frederick Amelung. However, more than one hand was involved. According to records of the Port of Baltimore, the "Brig Juno" a brigantine flying the swallowtail flag of the Danish Royal Navy docked in Baltimore Harbor in 1793, 1794, and 1795. During one of those visits the captain apparently visited a shop in Market Street, Baltimore, acquired the tumbler and had it further embellished with an image of his ship in full sail, marked "De Juno." After 1795, the ship plied the West Indies trade, never again returning to Baltimore's waters.
