These colors just make me happy!  I held off from collecting JAJ for as long as possible primarily due to shipping costs, but I caved when I saw this bowl set.  

According to an advertisement from 1973, these bowls were available in 1, 1.5, 2, & 4 pint sizes.  They were sold individually and in sets - a 1, 1.5, & 2 pint bowl set AND a 1.5, 2, & 4 pint bowl set.  Plastic snap-on lids were available that made storing left-overs in the refrigerator easy.  In addition to being used for mixing and storing food, these bowls could also be used to cook food in the oven.
