Glass, milk white glass of flattened ovoid shape printed in bright tones with a cluster of daisies and leaves, with a pierced rock and hovering butterfly, the reverse with pink peonies and rocks, the shoulders with an elaborate stylised petal collar, the neck with a pink classic scroll studded with florettes, the base with a two-character mark of Qianlong Emperor. By Wang Xisan, 1958-1962.
