 A very busy year for Mattels Kiddle Doll Line!By the time 1970 rolled around there was a global oil crisis taking shape and plastics, and especially vinyl which is derived from petroleum based products, was getting harder and more expensive for toy companies to buy.Mattel still released some Kiddles that year, but drastic cuts would ultimately lead to restructuring of what doll lines would continue and Barbie and her family were the star performers of the doll lines.
