Super Trooper insert
Super Trooper was available as a mail-order offer starting in 1988.
Pictured above is the insert that came packaged with action figures in 1988. It featured a mini-comic named "Operation Single-Handed". At the bottom of each comic strip was a certificate. When someone collected five of these, they could be sent in for a free Super Trooper.
