A while ago, I had searched for some ABBA paper dolls that were free and downloadable. Unfortunately, I didn't find any. So that's why I made my own ABBA paper dolls.
I did find some virtual ABBA paper dolls at stardoll.com.
Unfortunately, you can only dress up Agnetha and Frida. Bjorn and Benny are always stuck in their Waterloo costumes. :(
