Hi Nanna. Thanks for posting these interesting patterns. You're right, Isaac and Moses D'Azevedo were merchants and importers operating in Barbados and St. Thomas in the Virgin Islands, which of course belonged to Denmark at the time these plates were made. All of the views known so far are on St. Thomas. The view on the green plate is Mr. Kjaer's Residence and Observatory but I couldn't find the view on the brown dish. Unfortunately the maker of these pieces is unknown.
