Created in 1979 by the hands of Gillis Lundgren, Ikea's Billy bookcase turns 30 next month. Its unpretentious, clean and functional design has made it a sucess for 3 decades with over 40 million sold worldwide.

To celebrate its 30th birthday Ikea is bringing out a range of limited-edition Billy bookcases, in grafitti style Shakespeare quotes available in red, green or black.
The best selling bookcase in the world has also inspired Bloomberg to create an index tracking the cost of Ikea's standard Billy bookcase in 38 countries.
The minimalist yet versatile design has inspired millions to give it a makeover. Check out a few I have come across in Design Sponge, Marie Claire Maison and Apartment Therapy.
