Although an imaginative builder has surely created one, I don’t recall having seen a well-built LEGO marionette before. This puppet of King Gustav I by Nicolas Picot is brilliant, with great articulation and a solid reproduction of the king’s dapper uniform, in particular the upside-down curve-topped fences which serve excellent duty as epaulet embroidery. The king’s steely gaze is also particularly well done, and the mustache seems surprisingly accurate for made of only two pieces.
Paul Vermeesch also made a sweet marionette a few years back, I think I even saw it on here :)
