Many apologies to our Spanish readers, but I had no idea Spain has had a king for the last 35 years (needless to say I feel pretty ignorant!). Apparently Juan Carlos I took over after Franco died in 1975 and has been head of state ever since. Much like Queen Elizabeth, I guess his royal visage requires no identification so I had to figure out that he graced these stamps from my box by first coming across some more recent ones. These are from much earlier on in his tenure and I like the profile and monochromatic nature. I'm drawn more to the font and design on the left, but they're both strikingly modern for a monarch.
