Yes, this is just one grade! They are holding candles. Another interesting thing about the photo is that there is another set of twin boys pictured on the third row up from the bottom row. The twin boys are seated on the left, and they are the second and third boys in that row. Their names are Johnny and Jimmy Hardy. Although they share the last name of my husband, they are no relation! Another interesting fact about twin births in the small town of Sylacauga, AL is that there were actually five (5) sets of male twins in the town at just about the same age and none of them were related! In addition to there being a sale on striped shirts there must have also been SOMETHING IN THE WATER!
