I took the pictures for posts about Dolores, Audrey, and Enid at the same time, so I snapped a few with them together. Here they're lined up by year in ascending order: 1968, 1969, 1970. I wish I'd put my spare blue cord outfit on Enid (I'm saving it for Adeline post-repair), but didn't have the time to deal with clothes changes before picking up my kids at school. Once I've finished introducing all my dolls there will be plenty of time for more blue cord comparison photos.
And here's a shot of just the two blue cord girls together.
