Solidarity, brother!
The Prizes in Disguise contest was a promotion run by Hasbro during Generation One, starting in 1986.
Game pieces for the contest consisted of reflective iron-on patches. When the iron-on patch was used, it was possible to find instead an instant win ticket for prizes, including Transformers "action cards", a Transformers voice changer (of the Enemy variety), or a party with "life-size" Transformers! Among the "life-size" Transformers shown were Jazz and Skywarp.
You're the ones who didn't like our capering!
An entire toy commercial, complete with new animation featuring Jazz, Cosmos and Spike, was commissioned to advertise the contest.
Hurry, contest ends January 31, 1987!
