The Groningen Exhibition of Craft and Art Industry, roughly translated, was a big event, seeing about 300,000 visitors over its two-month run from June 15-August 15, 1903. Some accounts have the event running until September 1 of that year, but the official dates on the tickets and poster indicate that it was supposed to end on August 1st. It had a 60-page guide book and a commemorative coin. One would have to cross over a bridge, under a sign that read Tentoonstelling (Google translated: Shows) to enter the grounds. In one courtyard, a giant wine bottle stood two stories high, and in another, a fountain.
Halbo Kool, the living grandson of Halbo Kool (b.1873) and son of Halbo Christiaan Kool (I know, not confusing at all, right?), sent me these scans of Halbo Kool (b.1873)’s and Christina Kolle’s permanent passes to the event. In his notes, Halbo Kool says he’s not sure if they have had a stand for the H.C. Kool hat shop, but I’m fairly confident they would have, being located in Groningen and such good business people.
