Watermelon seed spitting contest

That is some good looking watermelon! I'm not exactly sure who these kids are; but they're in Perry, Oklahoma, and it's the late 1890s or very early 1900s. I found this photo in my collection from my Granny Annie, so at least one of the kids has the last name of Keeler. It reminds me of a song she taught me...
Fried chicken is mighty mighty fine
But nothing could be finer than a watermelon rind
So plant a little watermelon on my grave
And let the juice (slurrp)
Trickle through!
