Roto-Sphere - American Sign Museum

The most mesmerizing sign you’ve never heard of.

What weighs 1,000 pounds, spans 19 feet, and crackles with 256 feet of blazing neon?

It is the jaw-dropping, heart-stopping Roto-Sphere!

Legendary designer Warren Milks produced only 234 of these rotating Space Age treasures between 1960 and 1971. Today, they are the most coveted items in the industry—the definitive white whale for serious sign collectors.

Only a few in the world still spin—and one of these will be calling the American Sign Museum home!

We’re bringing a Roto-Sphere sign to the American Sign Museum!

But we need your help before it can spin in all its glory.
Our Goal: Raise $50,000 to fund this massive undertaking!

Help us restore the Roto-Sphere

To get this half-ton star running, our restoration team must:

Hand-craft 256 feet of custom neon tubing from scratch.

Replace all the massive electrical transformers.

Engineer a custom mount to install this 1,000-lb giant safely outdoors.

As a nonprofit museum, our mission is to actively preserve the art and history of American signage. You can put the mission into motion by being a part of this massive preservation project! With only a handful of these signs still in existence and even fewer in working condition, your gift will ensure this piece of American history keeps glowing for future generations.

Help us reach our $50,000 goal

The American Sign Museum wishes to thank Jameson Parker and North American Sign for their help in the ASM acquiring this Roto-Sphere and Alan Whitaker for his work to help get the star moving again.
