I remember going into junior high and seeing the #3 and thinking, "wow, those must be for us big kids!"
Seeing this the first time, I remembered the desks in my 5th grade classroom. The ink wells in #1 made me think of them. However, they didn't have the desk part that lifts for access to our supplies and they weren't for 2 students. The ones we had looked exactly like this:
