Liddle Kiddles

Kiddles were made of soft vinyl with painted facial features and rooted, brushable hair. The first, second, and third series (called "bigger bodies" by collectors) ranged from 2¾ inches to 3½ inches, while the Skediddle Kiddles were 4 inches tall and had a special mechanism inside the body which allowed them to walk, wave, and ride vehicles with the push of a child's hand.[3] The Kola and Kologne Kiddles were 2 inches, and the mini Jewelry Kiddles were ​⁷⁄₈–​1 ¹⁄₁₆ inches.[4] All the dolls were marked with "Mattel" or "MI", a date, and either "Japan", "Hong Kong" or "Taiwan" on the back of the shoulders or on the back of the head near the hairline.[3] The smaller dolls were marked under their non-removable clothing. Most Kiddle accessories were also marked. Some were marked with the Mattel seal, and some were only marked with a number.

The bigger bodies (the first ten dolls) were designed to resemble typical neighborhood children at play. The name Liddle Kiddles was taken from the words "little kid". Each of the first 24 dolls had detailed clothing and accessories that perfectly matched their theme and size. Wire skeletons inside the vinyl bodies enabled the dolls to be posed and re-posed realistically.[5]

The first series of 9 Liddle Kiddle dolls plus 1 special doll set was available only through the Sears and Roebuck Christmas Catalog. It was conceived in 1965 and released to toy shelves in 1966. The following year additional dolls were added to the Liddle Kiddle series, and the Storybook Kiddles series and Smaller Lucky Locket Kiddle series were introduced.[3] The small 2-inch dolls had no wires inside for posing and, unlike the first 10 and the new Storybook Kiddles, their clothes were not removable. In 1968, the last 6 additions to the Liddle Kiddles series were added, as well as 3 more Storybook Kiddles, new Skediddle Kiddles that could walk, the Kologne Kiddle series, and the Jewelry Kiddles.[3]

Mattel Designers kept making the dolls smaller and continued to maintain the use of real hair and clothes. Mattel also released a series of 4 2 inch tall kiddles dressed up in animal costumes and called Animiddles.[3] Ride and Run Skediddle sets consisting of a Skediddle walking doll and specially designed riding toys they could also use were introduced to the Skediddle Kiddle series.[6] 3 new Kiddle Kolognes were added. More Lucky Locket Kiddles were released in pretty new pastel locket colors.

1969 saw a new series of 2 inch sized Storybook Sweetheart Kiddles, portraying star crossed lovers, such as Romeo and Juliet, and Robin Hood and Maid Marion.[3] Also that year, Mattel introduced the Kozmic Kiddle series of 4 glow in the dark aliens in space ships, the Tea Party Kiddles portraying little girls dressing up as fancy ladies, each coming with a fancy child sized tea cup and saucer.[3] The Zoolery Kiddles were also released. These were 4 tiny animals about the size of the previous years Jewelry Kiddles that came in tiny cages that could be worn as Jewelry.[3] There were additional Ride and Run Skediddles added to that series too and Lucky Locket Kiddles were re-released in bright gold lockets that collectors refer to as "Gold Rush" lockets.

In 1970 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 led to Riddlers being discontinued. Many design concepts for new kiddles and several new series never made it to production.

Mattel records were researched by Paris Langford for the creation of her Liddle Kiddles value guide released in 1996. Paris included original concept art and a section showing pictures of prototype dolls that actually were under way at the time that Mattel stopped the line.[7] There were new concepts for fresh Jewelry Kiddle series, some dressed as bumble bees or tiny mermaids. The Bigger Body dolls with wire skeletons had a series under way centered around Circus Performers.[7] Many of these records have since been destroyed according to Mattel. Paris Langfords value guide now stands as one of the final records of these lost designs that never made it into production.
