From the Celebration Apple 1 auction site:

The “Celebration” Apple-1 is an original Apple-1 pre-NTI board that has many unique features, period correct power supply, original Apple-1 ACI cassette board (also populated with Robinson Nugent sockets), early Apple-1 BASIC cassettes, original marketing material, and the most complete documentation set of the known Apple-1 boards.

The “Celebration” Apple-1 is extremely rare not only because of the scarcity of Apple-1 computers, but according to Steve Wozniak, co-founder of Apple Computer, no known PCB boards of this type were ever sold to the public. At this time, this is the only known Apple-1 to show the signs of starting out as a blank original-run board and not part of the two known production runs, so this board appears to be unique from all other known Apple-1 boards.

The “Celebration” Apple-1 was authenticated by Apple Expert and Historian, Corey Cohen. Mr. Cohen believes The “Celebration” Apple-1 has the potential to be “powered up” with minor restoration, but has recommended against it to maintain the board’s unique configuration.

The Apple-1 Computer is considered the origin of the personal computer revolution and was built in Steve Jobs’ parents’ home on Crist Drive in Los Altos, CA. 200 were hand-built by Steve Wozniak, but it is believed that less than 60 are still in existence.
