I received an interesting postcard with all presidents from USA, 45 of them. The President of the United States is the head of state and head of government of the United States, indirectly elected to a four-year term by the people through the Electoral College. The officeholder leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces.
Nice matching stamps:
Abraham Lincoln, the 16th president of the United States from 1861 until his assassination in April 1865, issued on 12.2.2014. Uncle Sam's Hat, issued on 18.2.2017. Patriotic waves, issued on 12.1.2015.
