In January 2023, Argentina released a stamp showing an old friend, Les Eclaireurs Lighthouse located near the southernmost city in the world, Ushuaia, Argentina. I was fortunate to visit Ushuaia in February 2023 and took a boat tour to the lighthouse. That was one of the highlights of my trip.Les Eclaireurs L/H | Jan 2023 | G1320
