(Prague): Artia, (1964). A French language version of this very scarce little pop-up by the man who is called the genius of the pop-up genre, Vojtech Kubasta. It is number 2 in a series of three such small works for children and features five pop-up illustrations with text recounting the adventures of the two little butterflies. Kubasta was a Czech architect and artist who combined his skills to produce an amazing range of engineered books in addition to practicing a career as an advertising artist. He was the subject of an exhibition and catalogue of Ellen G. K. Rubin’s collection at the Grolier Club in 2014. Quite scarce, we find no copy of this title in OCLC, nor in Princeton or Toronto. A Kubasta Pop-up Threaded printed paper folder for pop-ups, 11 x 11 cm; five pop-up scenes on folded sheets with text. we have not removed the protective plastic covering ( not adhered) over the somewhat rubbed paper folder covers.
