Duffy London sell a range of canvases called Mini Glo. Probably the best in the range is the Vintage Shade Mini Glo-Canvas which features a print of a vintage lamp shade against a red wallpaper background.
Flick a switch and a light bulb hidden behind the canvas lights up, giving the illusion that the picture is a real working lamp. Clever, isn’t it?
It costs £55 and can be ordered from the Duffy London website.
