I’m kicking myself for having bought “a roll” of US postage stamps however many years ago it was that I last did that. I barely use the things any more. By the time I get around to finishing the roll (or my heirs do) no one will any longer recall who those people are that are portrayed on them. For all I know, it could be a different country by the time that roll is exhausted. (To say nothing of all the 1¢, 2¢, 5¢ and 8¢ stamps I still have kicking around to go with the 34¢, 36¢, 37¢ and 40¢ stamps I also have.)
