Last Saturday I got two postcards: one from Spain and one from Estonia.
The card from Spain shows a sunset over Barcelona.
King Felipe VI (from set of six) (issued 02-01-2016)
National Stamp Design Contest (from set of two) (issued 05-02-2018)
Museums (from set of three) (issued 26-03-2018)
with a great special postmark showing the Casa Milà
Thank You very much William!
