Artist's book by Jacques Caumont and Jennifer Gough-Cooper. "For the centenary on 28 July 1987, we have chosen a selection of 87 ephemerides from those already gathered for the days around Marcel Duchamp's birthday. Hidden behind this modest bouquest are some 2276 ephemerides (ever increasing), which will be published progressively as research and time allow. For those requiring a traditional chronological order, each entry is numbered sequentially and will be renumbered in the final EpheMeriDes. Selected reading for the beginner? Perhaps not. Nevertheless, we hope that this colourful kaleidoscope of Duchamp's life will intrigue, captivate and amuse all our readers." - from the preface. Printed in black-and-white.
