Stamps, 'con boina', from Spain

On June 28, 2009 I wrote: "Surprisingly, I have found it hard to find more than a few postage stamps depicting berets."

Surprising indeed, as there are so many stamps depicting a beret, or boina, from Spain alone:

Ignacio Zutoaga, Pio Baroja, Jose Maria Iparragirro, traditional Basque scenes

and depictions of the San fermin Festival in Pamplona.
