This had me scratching my head for a minute. Sweet raisin Danish! The fireplace and the display case are on the same wall! As we all know, they currently occupy totally opposite walls. And it doesn’t look like there are any glass doors between the lounge and the dining room! When did this configuration change?
My love for Norman Hackerman is well known but I barely noticed that it was him addressing the group here. I’d guess this to be pretty early in his tenure, so I’m calling it early ’70s. I recognize one person by the back of his head: that’s the Dean, Holmes Richter from Chemistry, with the shiny bald dome right in the back middle. He’s smoking a small cigar too. It’s good to be the Dean.
