Since I was writing in cursive, I must have been in third or fourth grade. Therefore, carbon dating would indicate this is from around 1968 or 1969. No idea why I got a 90 instead of 100, but it probably has something to do with my math skills (which are sucky to this day) on the map scale. At least I spelled Colombia right!
