When tourists become lost, overwhelmed, tired, inspired, bored, enlightened, confronted, hungry, upset or tipsy, get cheated or fall in love, perceptions change and surprising associations and experiences come to light. In trying to figure out a city, they are mostly investigating themselves. In each volume of The One Weekend Book Series M. Lorenz and a guest artist are given 48 hours to experience a city, document it and create a visual diary without the use of computers. What this results in is the documentation of a 48-hour search for visual entertainment and the definition of the city visited. On the one hand The One Weekend Book Series reports on places and situations not mentioned in the guide books, and on the other it offers an exhibitionistic glimpse of the personal state of the reporters. The present publication is a compilation of the first five volumes and gives a personal insight into the experiences of the author and his guest artists. Volumes 1 to 5 reported on Frankfurt, Copenhagen, Berlin, and New York City. For those volumes M. Lorenz invited T. Faulwetter, R. J. McCuskey, S. Ehlers, R. Riisholt, R. Lang, E. Schulze, E. Konig and Y. Sodeoka.
