Seems like they're "season photos", so a lot of Easter and Holy Week celebrations today.
I have to say I got almost perfect a Holy Week celebration in Sevilla in the 1920's (I'm Spanish, so only some hundred meters away but kinda wild guess for the year and only was two years off), and pointed Mexico instead of Guatemala for another, but nailed the year (1981) for a grand total of 902 out of 1000 points.
I only immigrated to the US in my adult life and I can't say I recognize Barbara Bush at a glance, so I was _also_ off by a few years and a few km on that one :( but still a lot of fun!
Oh, my first guess was off by only 1 year, and my final score was 3742, and my Avg. Years Off was 8.4, so it seems I have a pretty good historical memory, hahahaha.
This is a nice idea. Only issue are the ads - the ad on the bottom right is bleeding over the photo, there are two video ads playing simultaneously... Makes it annoying to play
