Fairly new to the board! This would be my 1st/? post. I've seen a set of hot wheels from the 90's I think? They have something to do with dairy queen. The cars are single pack but they are wrapped in a hot wheel logo paper that supposedly melts away in water. The back of the blister shows that a bicycle, cars etc could been won if a gold key is found inside the wrapper. Any and all info would be appreciated!
