Thirty-two years ago Bill Gates and Paul Allen celebrated licensing MS-DOS to IBM by posing for a photograph surrounded by what was then the very latest in technology.
On Thursday Gates and Allen recreated the photo in a significant moment for a relationship which has been incredibly patchy lately.
Three decades after the original was taken, many were shocked when Allen claimed Gates had tried to take full ownership of Microsoft from him even as he was battling cancer.
In his memoir released in 2011, Allen wrote: "I helped start the company and was still an active member of management, though limited by my illness, and now my partner and my colleague were scheming to rip me off.
"It was mercenary opportunism, plain and simple."
An epilogue in last year's paperback edition hinted at reconciliation.
After the death of Allen's mother, Gates suggested renewing their friendship after having had no contact for over a year.
Allen wrote: "I believe we will be friends again
"The history we share is more powerful than whatever comes between us."
It would appear Allen was right...
