Two Young Men with Early Bicycles, c. 1880s-90s Tintype Under Glass in Foil Wrap

I'm not an expert on the history of bicycles, but I believe the two young men here are standing beside "safety" bicycles, with pedals powering the rear wheel rather than the front one--an innovation of the 1880s. I love a young man with a bike, even better two, and love the mustaches, and the attitudes of these two. With painted trees and what looks like a lake view backdrop, and a couple of rugs under foot--or wheel, as it were:) As found, under glass with embossed gold foil wrap, all of which appears original and untouched. 

4" x 2 3/4" overall. Very good condition, reads sharp and crisp, with a bit of light soiling/dust appearing under the surface of the glass in a few spots--minor. I have not removed the tintype from the casing.
