Pair of elio schiavon modernist ceramic vases, skyline rooftops cityscape, 1960s Italian pottery

A rare pair of elio schiavon ceramic vases from the skyline series. Made in padua, italy, in the 1960s. Vibrant green and yellow in base colours. Sizes: 11 cm. Tall, with a diameter of 6.5 cm. The green vase is signed at the bottom by the artist. In near perfect condition. The yellow vase has a small crack under the glaze (not discernible by touch) and mostly visible from the inside, which likely occurred during the firing stage of the pottery manufacturing process.
