Hello everyone. I found some interesting pieces yesterday and I'm hoping to get some information. I found 2 film reels. They containing the 1982 theatrical commercials from Atari and Mattel. The Atari ad is known as The Fly and features Yars Revenge and has a bumper at the end announcing ET the video game. The other is for the Intellivision and has digitized news casters talking about the Intellivision games. Both are in fantastic condition. What kind of value am I looking at with these?
