Porto…Gaia — Metro (Portugal)
The printed caption only reveals the name of Gaia, Porto’s suburb; but the writer of this card, mailed in 2012 with Paralympics stamp and postmark, kindly explained the scene in detail. Grade: 1. We also have another copy, where the name Porto on the front is in white instead of red; also mailed in 2012, but with a different stamp. Also Grade: 1
