Allegedly from a Dutch computer magazine from the late 1980's. I really like this one, but I haven't found anything else about it. It is delightfully bizarre!
Someone over on Reddit made a post (HERE) that featured a bunch of art from an educational book about Windows 95. I'm sharing here as well, as these are nifty!
Crazy coincidence- Osborne Computer Corporation cooked this up for magazine ads. It's the second revision Osborne 1, so that places this in 1982 or 1983.
