Your phone has just become home to a tiny little collection of modern art.

On Wednesday, the Museum of Modern Art announced that it had acquired the original set of 176 emoji for its permanent collection.

These glyphs, designed for pagers made by the Japanese mobile provider NTT DoCoMo and released in 1999, were the first pictographs to make their way into mobile communication. It would take another decade for emoji to explode into an American phenomenon, when Apple integrated its first emoji set for the iPhone in 2011. There are now nearly 2,000 standardized emoji.
