It’s time for some nostalgia.

The PlayStation brand is 20 years old, and Sony is holding a big bash in Las Vegas to celebrate its gaming division. The festivities include a massive show floor with dozens of booths for big releases, indie games, and more. One of the coolest parts is a glass-case exhibit that contains all of the PlayStation consoles from the last 20 years, ranging from the original PlayStation to the PlayStation 4 20th Anniversary Edition system.

We snapped some pics of the display and gathered ’em up in a gallery for you. Take a look:

The original PlayStation, which is now 20 years old.
The PSOne, or the PlayStation slim.
And the PSOne with its monitor attachment.
The first PlayStation 2.

And now, the 20th anniversary edition PlayStation 4.
It comes with a camera.
And a gray controller.
