A very good idea, Roger, but Laurie is correct, this is from a photo of Jack Lincoln next to a bicycle.
The description of the site where I downloaded the picture reads:
According to an 1881 article in the Republic, Jack rode a bicycle 'like a professional in company with the sons of President Garfield and Attorney General MacVeagh.' This studio portrait, taken in 1885, reflects Jack’s enthusiasm for bicycling."
I am sorry this question was so frustrating to you - I thought the handlebar to be 100% revealing (the knobs look like those on children's bikes:
)
Thank you for your participation, Laurie and Roger! You win my best wishes for a nice evening!
