Young Man with (Iver Johnson?) Bike and Painted Trees, Antique Tintype

I like a boy with a bike and really love the expression on the face of this young man, especially coupled with his wide and short necktie, which angles toward his cocked elbow. I really love the painted trees on the studio backdrop too--which looks to have been hung outdoors, with real grass beneath his feet. Nice the fancy chainwheel on the bike, also, which I think maybe identifies it as an Iver Johnson, very late 19th century or so I think. Nice and moody. 

3 1/2" x 2 3/8" and in good condition.
