Natural Doll Co, Inc.
Quintuplets
Natural Doll Company of New York produced this set of quints.  They are 8" tall, with hard plastic torsos and legs.  The arms and head are vinyl. The dolls are jointed at the neck, arms, and legs.  The face is a nice quality with blue sleep eyes, molded painted hair, and a nurser mouth. They are drink and wet dolls. The girls are dressed in pink flannel blankets piped in  pink taffeta and tied with a pink satin bow.  The boy is identical but in blue. Their diapers are white flanneL.  They all hold bottles, the girls with blue tops, the boy with pink.  The box is a plain pink box with blue lettering.
This set was made for Grant's Dime Store.   The dolls are identical to the ones made by Natural Doll Company, so they were probably made by them and then packaged differently for Grant's.  
The dolls are 8" tall, hard plastic torso and legs with vinyl arms and head.  They are jointed at the neck, arms and legs and have blue sleep eyes and nurser mouths. They are drink and wet dolls;
The blankets are different from the Natural set in that they are shell stitched around the edges instead of piped with trim.
