- I would like, in turn, to thank Marc for putting such effort and
attention to the paper exchange. He had a really beautiful idea and
he realized it in a splendid and truly professional way. I would also
like to thank all the marblers who participated in the exchange and
especially the professionals who were kind enough to share their
exquisite works with the amateurs and novices. I thoroughly enjoyed
the experience and look forward to more exchanges in the future.
