Aluminia has produced this Brewery Plate in 1905. Tuborg. It measures 23 cm. x 18.5 cm. Perfect condition. In the 1880s when production at the Royal Copenhagen factory was dropping to a dangerously low level they were taken over by Aluminia (founded 1863), successful makers of earthenware, and since that time the two ranges, earthenware and porcelain, have been running in tandem.
