This collection is a must-have for any vintage toy or game enthusiast. Up for auction is a set of Mattel Electronics handheld games. This set includes Baseball, Football, and Basketball games. These games were tested and seem to play well although I couldn't get the hang of Speed Freak. If you were a kid in the 70's or early 80's you probably had a lot of fun with these. Get ready to experience all the fun and excitement these games have to offer!
