This pretty butterfly arrived on June 17 from Finland. The photo was taken by the sender in Greece last year, and made into this postcard. I did a search, and found that the butterfly is a Scarce Swallowtail (Iphiclides podalirius):
She says it took a while to get a good photo of the butterfly, but she likes this one. I do, too. It is called a Scare Swallowtail.
This little bird looks very happy. Is it some sort of Finnish swallow I wonder?
