A Bitossi 'Rimini' blue glazed earthenware jar and cover, 1950's, designed by Aldo Londi, with bands of geometric sgraffito decoration.
In very good condition, there are a few minuscule glaze chips on the rim of the jar and the underside has been applied with blue velvet which obscures the marks - I've not attempted to remove it.
13.2cm high, not including lid knob.
