Mikory from Mikory's ABBA Blog just posted an image of Bjorn's passport from 1972 earlier today for his daily pictures. (Wow, I only have weekly pictures.)
Anyway, I decided to translate what it said on the image. Here are the things I've discovered:
1) Bjorn spells his second name with a K.
2) Bjorn's hair color is "Between Blond", "mellanblont" in Swedish.
3) Bjorn's eyes are just plain blue, not grayish-blue or anything fancy. (A friend of mine told me that Bjorn's eyes were brown and I ended up painting his eyes brown. I had wanted to find a picture of the real Bjorn's eyes, but we had a very long power outage because we had an early snow. I painted over his eyes with a grayish-blue color.)
Pretty interesting... At least now I know what his hair color is. I have to tell that to all of my friends....
