When the Macintosh design was finally locked in, Steve Jobs called the Macintosh team together for a ceremony. “Real artists sign their work” he said.  [photo credit: Norman Seeff]

So he got out a sheet of drafting paper and a Sharpie pen and had all of them sign their names.

The signatures were engraved inside each Macintosh. No one would ever see them, but the members of the team knew that their signatures were inside. And just as they were aware that the Macintosh’s motherboard was also designed as elegantly as possible.

Jobs called them each up by name, one at a time. Burrell Smith went first. 
Jobs waited until last, after all forty-five of the others.

He found a spot right in the center of the sheet and signed his name in lower-case letters with a grand flair. He then toasted everyone with a glass of champagne!
