There are six costumes sleepers that were produced by Coleco.
These cute outfits came out in 1985 and were only sold separately packaged until . . .
. . . later, in 1986, as Coleco was clearing out stock, they could be found on boxed kids. (Ref#2, p. 90, Ref#4, 1986 Iss. 3, p.5)
They are two versions of each sleeper. The first set that came out had only the green Cabbage Patch Kids logo on the right breast. They were all made by the IJ factory in Korea. The second set also had an embroidered crest of their animal on the breast under the logo. These were made by the LF (China) and IJ (Taiwan) factories. The LF version of the second set is easier to find. I’m not even sure if IJ made all of the second set.
The ‘double tag’ seems to be the earliest. The square version is most likely the newer one. I am unsure why some were coded with a sticker.
The most obvious difference between the IJ and LF versions is the crest. On the IJ version, it is embroidered directly to the fabric. In the LF version, it is an applique that is glued on.
