Through the latter half of 1964 and on into 1965 small groups of young people would converge at midnight every Saturday at the foot of a statue in Amsterdam. The statue was that of an anonymous small boy, the Lieverdje. It was a gift to the city from a tobacco company, and, as far as the Saturday night gatherings were concerned, it was less the statue itself than these donors who were important. For this was the spot chosen by Robert Jasper Grootveld to promote his campaign against the use of tobacco. Each midnight event would consist of a speech by Grootveld followed by the burning of something. On at least one occasion it was the statue itself which went up in flames.

Provocations in Amsterdam

The events at the Lieverdje were part of a one-man campaign. It started with Grootveld defacing cigarette advertisements with the word ‘Kanker’ or the letter ‘K’. As a consequence of legal action by advertising agencies for this vandalism he was repeatedly gaoled. From this first phase of his campaign he moved on to establish an ‘Anti-Smoking Temple’. Here he

Then in April 1964 Grootveld launched a citywide game called Marihuette. Although this name was based on ‘marijuana’ Grootveld claimed ‘marihu’ could consist of anything that smoked – straw as well as grass, so to speak – apart from tobacco. Teun Voeten says the idea of the game ‘was to demonstrate the establishment's complete ignorance on the subject of cannabis’ (1990). Its rules were distributed by means of a chain letter (a pre-Internet mechanism of viral communication), leaving receivers able to add to the rules as they wished. As part of the game Grootveld filled cigarette packets with marihu, of any burnable sort, and smuggled the packets into vending machines. The rules themselves, characteristically of this sort of game, were fairly inscrutable, largely having to do with getting numbers of points in relation to being arrested, rather than avoiding arrest, for marijuana usage.
