Love the design and right now, this vintage 'pop-art' hanging lamp is available for next to nothing too.
Details are scarce, with the seller claiming it is from the 70s or 80s. If I was a betting man, I'd go for 80s, just because of that bold yellow colour, which is reminiscent of the era. It's made of plastic and has a diameter of a 34cm, with no cracks or indeed, wear and tear.
Just a penny right now on eBay.
