Super Crisp Modernist Tower Whimsy with Sliding Center Cage (Copy)A very crisp, very modernist minimalist feeling whimsy, including for the center ball in cage, which slides allowing for viewer participation! (And it will hold in the "up" position when stood on end.) I love a tower whimsy, and a modular sculpture, and this feels to me like the Sol Lewitt of whimsies! 7 1 4" t x approx 1 1 4" x 1 1 4". Excellent condition, beautifully executed, mid 20th century I presume.
