The world's smallest magazine cover has been printed in 3D. IBM's microscopic 3D Printer now holds the title of printing the smallest magazine cover in the world. IBM and National Geographic Kids revealed the cover that is small enough to fit on a single grain of salt 2,000 times.

This has been claimed the world's smallest magazine cover by The Guinness Book of World Records. The gray-scaled version of the NatGeo Kids' cover is invisible to the naked eye. Dr. Colin Rawlings is a physicist at IBM Research and he said that even if you had a microscope, you would only be able to see a very blurry version. If you want to see the world's smallest magazine cover in its full form, you would need an electron microscope.
