This is a unique block of four stamps featuring President Luis Cordero from Ecuador, issued between 2011 and present day. The denomination of these stamps is 1 US dollar, and they come in a variety of colors, with a multi-color design. The stamps are mint hinged and have a very good grade. They have not been certified for authenticity but originate from Ecuador. This block of stamps would be a great addition to any stamp collection, especially those with a focus on Latin America.
