If you're looking for a cultural fix in Southern California, be sure to check out the Portuguese Historical Museum in San Jose. John Mattos currently has 6 pieces in their current exhibition, a remembrance of the 50th anniversary of "Vulcao Dos Capelinhos" in the Azore islands off the coast of Portugal.
The Capelinhos Volcano was a submarine volcano that erupted on the 27th of September, 1957 at the eastern side of Fayal island. The volcano raged for thirteen months before going to sleep, having changed the landscape forever. Many refugees from the island came to the United States under the protection of the Azorean Refugee Act, initiated in part by then Senator John F. Kennedy.
So now you know.
The exhibition includes these gorgeous stamps by John Mattos.
