Photo Number 214

I have many questions about this photo...the man on the right..what is hanging from his pants? The little girls have huge hair bows..weren't these popular in the 1920's?  I am wondering about the pipe behind them, were they standing near a field?  The two gals in the center could be sisters, children usually stand in front of their parents in a photo, and I believe that is exactly what these little girls are doing.
Thanks for stopping by, do come again:)
