SURE! Charming Old Snapshot with Emphatically Emoting Children and Painted Step

It is absolutely the SURE! painted like graffiti on the face of one step here that makes this photo for me, though the faces of these two little kids are pretty excellent too--their emotions seeming positively beyond containment! With nice shadows too, including that of a figure in hat looming over them, the picture taker one presumes. 

4 1/2" x 3 3/8" snapshot. Good condition, with some black photo album paper residue on the reverse.
