heart wheels

i was recently going through a junk pile and i ran across a steel wheel that had heart shapes in it......i was not able to get it but i know that it had the ford/mopar 5 on 4 1/2 bolt pattern......i am not sure if it was 14 or 15 inch ......i was told that they were used on vans in the 70s ........has anyone ever seen these or does anyone have more info on these wheels???
