Judging by the ashtray and the fact that the copy references the
"terminal on your desk," I'd guess this is from the early 1980s.
The copy ends with: Tomorrow's automated office will clearly include Electronic Mail. But like the rest of the Office of the Future, it's available at Honeywell today.
Fat lot of good that will do you if it's the early 80s and you're the only one with email capability.
