Balthazar Wigand specialised in views of Vienna's important buildings which he incorporated in work-boxes, caskets etc. Leo Schidlof called him the Blarenberghe for Austria, where he was very much sought after.

In the present case the box is very probably made by Nicholas Rozet, whose shop 'The Nine Muses' was founded in Vienna around 1790, selling silver and objects of vertu. He specialised in the production of steel-mounted work-boxes, writing sets and travelling cases, (see back of the catalogue for an example of a travelling necessaire executed for King Ferdinand VII of Spain). In 1873 the shop was renamed after their owners Rozet & Fischmeister and is still in existance today
