The Cocktail shaker in question was by Desny, a famous Paris firm specialising in art deco silverware in the 1920's. This was a set of a shaker and six matching cups and very rare. Most expensive cocktail shakers tend to be figural in design (e.g. lighthouse, rooster, penguin, zeppelin, airplane, fire extinguisher etc. $2k -$15k for good originals) but this set appeals to both shaker and art deco collectors so competition is fierce, 32 bidders in this case.
