1950s Quaker Crazy Rings Premium Set

One of the greatest toy ring premiums of the 1950s was the Crazy Ring Set sponsored by the Quaker Oats Company. For only 25 cents, the lucky recipient received a total of 10 crazy rings, one for each finger, including a siren ring, pencil sharpener ring, 2 dexterity puzzle rings, squirt ring, ship in-a-bottle ring, whistle ring, hand-shaking friendship ring, jingle bell ring, and, amazingly, a meteor ring that the ad attested "contains an actual meteor piece from outer space" (mine is missing the stone, so I can't evaluate that claim).

Here's the original ad for the Crazy Ring Set:
