I've since completed my pink set so don't need any more of these. I do have a spare Pink 7.
I need Blue 1 like you and also Blue 14, 20, 24, 26, 49 and 54. I have spare Blue 3, 17, 43, 55 and 69.
So a part from Blue 1 - I'm after six cards and so are you!
Let me know if you have spare of the ones I'm after.
Cheers, good to hear from a fellow Abba card collector.
