Until the 5th of next month, you can choose what you want to see in the blog on days 11 and 12. You can choose people (one of the members or someone related to ABBA), a place where they had been or a costume that they wore. I'll put all the pictures I have. Send all your ideas to my email: email@example.com.
I won't accept ideas in comments, just in mail. I am waiting for your ideas, kisses.
