I'm looking for Ethnic dolls that I used to have as a little girl.?

When I was a child - 30 years ago, I had these six ethnic dolls. Each one was enclosed with a plastic base with a clear plastic cover. I could take them out and play with them. They were probably 8 inches tall and plastic like Barbie dolls. One was Spanish with a beautiful red dress and black lace on the ends of the ruffles. Another was from Holland with blond hair and blue eyes. Each doll had clothing from her culture. Unfortunately, I can't remember the others. I had been saving these dolls for years, but my mother gave them away. It's very possible they were purchased in Syracuse, New York or Kingston, Ontario. Has anyone ever seen anything like this and/or perhaps know where I might find something similar? Thanks for your help.
