Lyseth Belt and Theo Butterhof of Antiquariaat Isis have been preparing for the great day for weeks! On Twitter, on their websites, and in the press they promoted their great idea to not only hold an ILAB Pop Up Book Fair but to create a whole ILAB Pop Up Book Fair Street. Flags were printed, posters were fixed, and the decorations for the many shopping windows in Folkingestraat were arranged. See how the ILAB Pop Up Book Fairs on UNESCO World Book and Copyright Day 2015 are celebrated in Groningen, Netherlands. Marvellous! Fantastic!
