I went to elementary school in the 60’s and 70’s in California, and not only did we not have all the different pictures of Presidents, we didn’t even have any picture the President who was in office at the time (Nixon, and then Ford). Neither did my junior high school or high school. My nephew’s elementary school, currently, does not have any pictures of the President and never has. I always thought that was something you just saw on TV, like on Leave It To Beaver.
