Signed modern raku box, pretty brutalist grip and stunning colors

Beautiful modern raku box. Signature incised handwritten under the base but I do not know the artist and I do not find... "b. Guymet xii" Box with its original lid and taken in a very artistic way. Small gaps are to be noted on the plug but as the form is free, we can think that it is done on purpose. A shrapnel in the lid barely visible but present. The lid does not find its place quickly, it must be turned in the cup to find its place and it simply lands, so it can fall easily because nothing holds it. Stunning colors: shades of blue and grey pulling towards black. High-quality contemporary work. Pot diameter: 10 cm - total height with lid 14.5 cm.
