Portlligat is a small villages on Costa Brava, Spain. The genius surrealist painter Dali (need i say one of my favourites) lived there, and his house got converted into The Casa-Museo Salvador Dali - a detail of which (one of his famous eggs) is represented with this card :) I have become a true Dali fan when I visited his hometown Figueres during my highschool excursion. The Dali Theatre and Museum was such an interesting experience - it was 'something else', an engrossing attack to all my senses :=D
It is easy to understand now why i loved seeing this card in my mailbox!
Thanks to CaCrr and gabriela/gaquero - also for the interesting stamp :))
