That is rather lovely, but how is the unicorn band made - painted on? I wonder how well it will last.
The tapestry set 'La dame a la licorne' is in the Musee de Cluny in Paris, and well worth a look for anyone happening to find themselves there.
According to the webpage, the unicorn emblem is produced via printing. It also mentioned that the resin is mixed with some type of glass substrate-based dye so the pen "glitters" at certain angles. I guess we'll have to see the actual pen to understand the effects this creates.
Also, the brass ring is printed with the words "A Mon Seul Desire", which is also from the tapestry.
(On a side note, the Medieval Museum was one of the places I skipped during my previous sojourn in Paris... went to Giverny instead, since I figured there's less chance to visit Monet's Garden than a museum inside Paris proper).
