The card is written in old German ("Altdeutsch") handwriting, which is no longer used today and is not taught at school anymore; and in Greek. So, the handwriting is not "bad", as Darkfish suggested, but it is a completely different handwriting font that is no longer used today and is not known by many anymore. I could read it a bit in my school days, but I do not recall it anymore.
