The Consumer Electronics Show (CES) was an important venue to introduce new computer technology throughout the 1980s and to today. I believe this image shows the main entrance to the 1982 or 1983 winter event, typically held in January in Las Vegas. If you look at the Panasonic booth in the photo, it shows what I think is a JR-200U microcomputer, which was introduced in 1982.
