Jack Puzzle

$98.00 at Museum of Contemporary Art Chicago.

Six uniquely notched brass bars precisely interlock in a single configuration to form the classic "jack" shape. Expertly crafted with exact milling and weighing just over a pound, this piece serves as an elegant desk accessory, sturdy paperweight, and captivating diversion. However, a word of caution: once dismantled, reassembling it may prove quite challenging.
