I wish I had a picture of dolls I'm trying to find but seem obscure or I have no idea how to search for them.
They were about 5 inch tall fashion dolls. Very late 80s/early 90s. I remember one was a brunette with a ponytail. They all had curved arms that curve like parentheses () to their front. I've got them in storage. I just can't remember them.
I also remember a ballerina doll that I had. Her feet had a joint in them at the ankle to where you could bend them flat to stand or on pointe. I believe her outfit was molded on, but I think she had 2 different tulle tutus (one was pink and maybe there was a purple). Blonde doll, blue eyes, about 9-10 inches tall. I believe she came with a barre and maybe a mirror. She had a pink molded crown on her head and you pulled the crown up and pushed it down. That made her spin. I think she also had removable leggings. Joints let you pose her legs and arms too. I know it's not Dancerina Ballerina from the 1960s, Dancerella from the 80s, My Pretty Ballerina by TYCO, or Dancing Pretty by Mattel. This doll was made in the late 80s/early 90s and I believe that it was part of a line about dreaming for some reason. Like there may have been a gymnastics doll, maybe a roller skating doll. It's driving me nuts.
Another "obscure" type toy I guess would be paper dolls. I was obsessive about paper dolls and am sooo tempted to start collecting uncut paper dolls from my childhood like Punky Brewster, Monchichi, Tropical Barbie, Heart Family, Moondreamers, etc. I had a black shoebox full of them and loved them. I also loved the 1970s Ginghams paper dolls.
Marshmallow Babies by Playskool were a bit obscure too. I'd love to find one on ebay because mine from childhood is not in the best shape. They are so expensive though! The only one on ebay is over $100. And it's blue. Mine is green with short hair and a green/peach romper. I even have the doll's original socks still.
