Whistling Barefoot Boy with Apples

While  scouting cool stuff for my farm store, I found this classic vintage framed photo of a boy in overalls with a basket of apples. His lips are pursed - I guess he is whistling. It looks to me like a hand-colored  photograph.  In tiny white letters on the bottom left it says "Copyright 1901, Campbell Art Co, Elizabethtown NJ.  In the right-hand corner  it says 276, G.W. Wacce, Phila.  Perhaps Wacce is the photographer.

In an Internet search  I found a site devoted to the Campbell Art Co, and have sent them an inquiry; I'd love to know more about this image.
