It seems like the picture of the "home computer" could actually be real since visions of the "future" were often way too enthusiastic about scientific progress in that form. Remember what people in the 60s thought the 1980s would look like?

The television monitor in the upper right-hand corner is suspect, though... it looks like it could have been added later since its coloring and shading are a little bit awkward compared to the rest of the scene.
