The stamps really pop against the black envelope.
Almost every stamp looks wonderful on a black envelope! But I don't find them often (this was a gift included on an online order of stationery).
Beautiful postcard, and indeed the stamps look great against the black background!What is the subject of the stamp, left of the lighthouse stamp (I cannot see it that well, have a small screen now :-) )?
It's a picture by famous photographer Antonio López. According to Correos' explanation: "'House of Antonio López Torres', 1972-1980, depicts his uncle's house with tile floors, a dresser, a lamp and another room in the background." You can see the sheet here.
Oh, sorry, you said "left"! It's from a series depicting a part of the history of Spain (sort of) in comic, from 2001. Drawn by Gallego & Rey.
It's a representation of king Charles V or Carlos I. I hope you can see it bigger here.
Thank you for coming. All your comments make me extremely happy.
