In November of 1967, Mattel rolled out a new promotion in magazines across the country. The Million Dollar Christmas Sweepstakes included a seven page ad with a cover page; five full color pages of dolls and toys; a list of participating stores; and a lucky number coupon to take the store to see if you were a winner. Each winning coupon, verified by a store employee, could then be mailed in to receive a $100 gift certificate for Mattel toys from the store.
My copy is from Family Circle magazine, so the print quality is not as good a some others I have seen. But what you see below are high resolution scans of the dolls that were included.
