In the kingdom of bubbles - Sketch Book IV of John Benjamin Maneval

Share Button

John Benjamin Maneval left us a lot of color sketches.

In this fourth book, we grouped some artistic designs and beautiful sketch work.

In our spare time, we still will scan its books to present its best drawings.

Feel free to leave us a comment at the bottom of this page.

  1. Hello, I am an architect and professor of architecture at the Grenoble school and I am currently carrying out research on hulls. I have known JB Maneval's six-shell bubble for a long time, but I had never seen your site before. Thank you for this wonderful compilation work, and above all thank you for showing us your father's sketchbooks ! It’s very informative. Could you specify the dates documents that you scan and make available to us ? It would be a real plus for research.
    Thank you in advance and again well done for all this work !

    1. Hello Pascal
      thankyou very much for your comment, unfortunately no sketchbook is dated, however, it would be logical to imagine that all this dates from before 1968.
