In all probability the ceramics of this lamp was made by the Parravicini company. Ivo Sedazzari designed several items for the company.

The glazing of this table lamp is also very similar with the glazing of the famous Italian ceramics company Gabbianelli. This lamp is reminiscent of the Longobarda (Lombard) lamp Marcello Cuneo designed in 1966.

Several other companies produced similar colourful ceramics. The Italian Sicart company is a fine example. Especially the Pino Spagnolo designs are reminiscent. Also SC3, the firm that produced the Philips Venezia lamp, you can find it over here.
