Stuart's Creations 1965? MN Twins Knit Doll

I found a Stuart's Creation MN Twin's Knit Doll. I think it is from around 1965. It is a cool old piece of Twin's memorabilia. I am a big Twin's fan, so anytime I come across this stuff, I get super excited. Can anyone tell me anything else about this? I would love to learn more about it.
