My mother had a great uncle (to old for me to have met), who was 10 years old when Lincoln was killed. He always told a story about how, as a boy, he climbed a telegraph pole to watch Lincoln’s funeral cortege pass through downtown Buffalo NY and stop at the city hall.
Years ago, when visiting Buffalo, we stopped by their history museum, which had a large Lincoln exhibit with many photos - one wide-photo showed Lincoln’s funeral cortege stopped at City Hall. And just across the street - was a small figure 2/3 up a telegraph pole
Wow. Talk about outside confirmation.
