Add to ORKGBlack and white photograph of Yourdon family members and friends on a picnic. Ed Yourdon's notes: "Mystery picnic scene. I really don't know anything about this photo -- no idea when it was taken, or where. I'm pretty sure that the man on the left, with the funny sombrero, is Marvin Yourdon. In the middle is, I think, Ike Yourdon. But I don't know who any of the other people are.
