Nintendo Entertainment System ad
This advertisement for the NES and its peripherals was published in a Hills Back To School sales flyer in the summer of 1986 and was shared earlier this year on Twitter by @HillsDeptStores. When I first saw it, I thought that the date was wrong because I don't remember the system being sold independently of R.O.B. and the Zapper back in 1986, but it is accurate. The entire flyer has been archived on Newspapers.com which shows that it was published on July 26th, 1986.
That's a pretty good price for the NES and its games 35 years ago, even if the person in the ad is trying to play World 2-2 of Super Mario Bros. with a light gun.
