This event was awarded a royal grant and ran for the month of July. [Note: Alamy.com has a licensable image of a Diploma of the National Industry exhibition, 1825, Haarlem.]
The catalogue initially sounds more like a haberdashery shop – exhibits of linen, cotton, wool or cotton threads, leather items and bindings. But it also included paper and typography products, wood and joinery products, pottery and earthenware, metal products, chemicals, glassware and crystal. Its industrial heading appears to be more about art, as it includes anatomical figures, marble bas-reliefs, portraits of Da Vinci and King William. A raft of scientific instruments and machines, surgical equipment, a broad range of fabrication utensils and luxury consumer equipment.
The second part of the catalogue lists extraordinary exhibits that include a large telescope, new styles of locks and a model of a floating bridge. There is no information on the venue used nor any visitor statistics.
