Try to guess the year a photo was taken. After about 40 tries my high score is 4621 -
1 - a hunting party in 1909. I was a year off, complete guess
2 - a Springsteen concert in 85, a year off
3 - an office photo in 89, a year off based on the style of computer
4 - a NYC street from 1977, 2 years off, educated guess based on fashions
5 - Trump as president, guessed exactly in 2018
My previous tries weren't as successful. I find the early 20th century difficult. And actually, the last 15 years are kinda interchangeable.
