vintage baby dolls - 60s Uneeda baby doll & big babies with sleep eyes

Lot of three vintage vinyl baby dolls, mid to late 60s vintage? There's two of the big babies (19 1/2" long) and one small baby (marked Uneeda, measures about 14 1/2" long).

All have sleep eyes in very good condition, though they have some general wear and tear from being played with. One of the twins has a much lighter head, we don't know if it's original, or fading from age.
