They're adorable and roughly the size the beloved Dawn doll of this author's childhood. They're Little Miss Dollikins, and they were designed as a competitor to Dawn, actually, back in the early 1970s, measuring in at 6.5 inches to Dawn's 6. Dollikins had already been produced in larger sizes for years at that point, competing with the unstoppable Barbie at just over 11.5 inches high, and before that produced in larger sizes of about 19-20 inches.
In the latest episode of the T series, you'll see the three Little Miss Dollikins I had as a little girl. These were three of my earliest dolls as a child. I don't even remember what the boxes looked like, but thankfully here comes the Internet to to the rescue! Below are some photos from a simply smashing post on the Who's That Doll Facebook page. (One of mine, the blonde, I believe was branded Triki Miki as shown below.)
The image of Little Miss Dollikin fashions above may just solve one of the mysteries around my own dolls. I remembered what clothing the blonde and redhead were wearing when I got them, because I never really changed their clothes, but I wasn't as clear on the brunette. I was pretty sure she was wearing the denim button-up shirt and bell-bottom jeans that you see on her in the video. And lo and behold, it's one of the outfits above, lower left part of the image. So yes, that's a Dollikin outfit and not a Dawn one. But I could not find any Dollikin online that came dressed in that outfit as I believed mine was. Maybe the brain trust out there can clear that up!
