Sugar Crisp Cereal Prize

Found this in a packet of old post cards I purchased. It was a neat prize that probably sold alot of cereal. The 3-d still works great. Not sure of the date, but I am thinking the 1950's. It seems like there were a lot of good prizes back in the day ! I don't think that there is hardly anything given away these days. I remember back in the 60's buying my cereal based on what was inside. Thanks for looking. T.G.
