When I was a kid, I had a metal Tonka Toy crane very similar to the the yellow one in this collection of playthings decorating the walls of New York's B-Bar. Mine was a finicky object whose mechanism was easily tangled, thus putting the whole thing out of commission. No matter how careful I was, the picker-upper part of this piece never seemed to be able to lift anything bigger than a Matchbox car and easily dropped open, spill its contents all over the floor. Dad would re-adjust its riggings, and then I'd start picking things up all over again...that is until it got all tangled up again. And of course, Dad came once again to the rescue!
