Actually that was the grand prize that Revell awarded the prize winner in the Revell sweepstakes. All you had to do was cut the Revell brand name from the box or reasonable facsimile, put your name and address on the back, put it in the envelope and mail it. That label with your name is what they draw among the thousands. Only supposed to put in one label out per envelope. It didn't matter if it was a large or small label. I beleive 75, 76 and 77 were the years the sweepstakes were done. I entered the sweepstakes around 76. I sent in alot of envelopes. 1st prize was the Cessna 150 or 152. 2nd and 3rd prizes were Harley Davidson dirt bikes, 4th prizes were a 6 pack of model kits cars , boats and planes. 5th prizes were 3 pack of model kits; a car, boat and plane. There were numerous winners for the 4th and 5th prizes. There might have been a 6th prize, but don't remember what those were. I was one of the 5th prize winners of the 3 pack of kits. My box came in the mail had the 1/16 Tom Mc Ewen Army rear engine dragster, 1/32 scale Hawker Harrier jet and the Prinz Eugen battle ship model. Still have the dragster and Eugen battle ship models that I built. Anyone else enter this contest back then? Would love to read what others won.
