In 1971, Kjartan Slettemark came across a campaign poster featuring Nixon's portrait, innocently sent out by the American embassy. It hung on the studio wall for a few weeks when one day he asked for an advertisement poster for Gevalia coffee that he had seen at his local shop. The advertisement image showed a smiling woman lifting a coffee cup. When he cut out the woman's hand and placed it on the Nixon image, the size, colour, and lighting matched perfectly. He immediately wanted to print the work as a poster but could not afford the printing himself. He added the text "Moderna Museet - Open every day 12 - 22" and submitted it for printing at the press used by Moderna Museet. The poster was printed, and the bill was sent to Moderna Museet. The next morning, Stockholm's advertising pillars were filled with Nixon posters. Moderna Museet reacted and wrote a letter to the artist prohibiting him from selling or distributing the image. Despite this, the image continued to appear around the city. Kjartan Slettemark continued to work with the image, cutting away the museum's text and making it even more similar to Gevalia's campaign image. The fake Gevalia poster was political art. A protest against the US war in Vietnam and against American imperialism. In 1971, the Gävle company Gevalia had been acquired by the multinational corporation General Foods – thus finding itself on the enemy's side. The story continues as the advertising text is cut away and gradually develops into the collage series "Nixon Visions," where the president's face is distorted in various ways.

The king Gustav III viewed coffee consumption as a threat to the public health and was determined to prove its negative effects. It is said that he decided to carry out an experiment on two prisoners. Two twins had been tried for the crimes they had committed and condemned to death. Their sentences were commuted to life imprisonment on the condition that one of the twins drank three pots of coffee every day while the other drank the same amount of tea, and this for the rest of their lives, in order to see if the coffee affected their life expectancy. Unfortunately the king died before the final result of his experiment: the first twin died at the age of 83 and he was the one who drank tea!

A 44-year-old man presented in May, 2001, with muscle cramps. He had no medical history of note, but volunteered the fact that he had been drinking up to 4 L of black tea per day over the past 25 years. His preferred brand was GoldTeefix (Tekanne, Salzburg, Austria). Since this type of tea had given him occasional gastric pain, he changed to Earl Grey (Twinings & Company, London, UK), which he thought would be less harmful to his stomach. 1 week after the change, he noticed repeated muscle cramps for some seconds in his right foot. The longer he drank Earl Grey tea, the more intense the muscle cramps became.

After 3 weeks, they also occurred in the left foot. After 5 weeks, muscle cramps had spread towards the hands and the right calf. Occasionally, he observed fasciculations of the right adductor pollicis and gastrocnemius. Additionally, he noted distal paraesthesias in all limbs, and a feeling of pressure in his eyes, associated with blurred vision, particularly in darkness...

The patient assumed that there was a relation between his symptoms and his tea consumption, and stopped drinking Earl Grey after 5 months, reverting to pure black tea again. Within 1 week, his symptoms had completely disappeared. Symptoms also remained absent if he completely withdrew from tea, which he did in the nature of experiment, for about a week. He found that his symptoms did not recur as long as he consumed no more than 1 L of Earl Grey daily.

When last seen in November, 2001, neurological examination, nerve conduction studies, and electromyography were normal. He was still drinking 2 L of plain black tea daily (his entire fluid intake), and had no complaints.
