I have come across a Monart mushroom lamp and am concerned in case it is a fake. There is no sticker and the pontil is completely ground down into a smooth depression similar to what I have seen on Whitefriars glass. The glass is a light green colour with pale yellow, and has gold inclusions. The shade is held in place on a fitting with adjustable arms with screws as I have seen on your website. It has a glass base and shade and looks very similar to the lamp on your Monart lighting page under the heading P23 Pedestal base.
I would be grateful for your comments as soon as possible.
