Lennart Grebelius is an artist who works with the concept of time, probability and chance. His work consists of, among other things, minimalist books: “On The Death of John Michael Lamb”, “Kidney for Sale”, “Final Meal”, “Who Am I?” (this book illustrates a sexual orgasm; about 300 million sperms in 300 volumes with 200 pages in each book).The invitation card and poster for his exhibition at the Borås Konstmuseum has a similar dissecting approach to the opening hours of the exhibition.
