A lovely design and one that's no longer in production – but this Carlo Santi lamp by Kartell could be yours via eBay.
Designed in 1972, it's described as a floor or side lamp, standing around 60cm tall. The base is tubular steel, the shade is plastic and according to the seller, the original item is in 'very good condition' with 'only marginal signs of wear'. It also works, most importantly.
Loads of images on the seller's page. If you want it, the lamp is on a 'buy it now' for £290 or you can make an offer.
