Blue tile work and caravel from Joana from Portugal

I received this amazing unusual postcard from Joana from Portugal thanks to one of I offer tags on official postcrossing forum. Joana wrote on the postcard, that it (the postcard) mixes two important thins of the history and culture of her country: blue tile work and the caravel. She wrote also, that tiles are very popular in Portugal to decorate with them homes or monuments. I like this decorative tiles very much and I’m very happy to get this beautiful postcard :)
