This is an old post card, and on the front is a really cool old bike shop. I am not sure of the exact age, but it is at least 1892. I say that because there is a candle stick telephone on the counter, and those were first available in 1892-3. Note the awesome New Departure bell display next to the phone on the counter. Also of note are the carbide lamps in the display case. That may be an early’ish motorcycle the man is sitting on, I am not sure though.
