Thought you were talking about me!
They are wonderful photographs. I book marked the site!
My fathers family is from Aberdeen Scotland. I've got a photo of my great grandfather who was in a bicycle race about the time these were made. I have a silver pocket watch engraved inside on the back (the back opens to reveal) "2nd Prize, for, 16 hours, amateur bicycle contest, won by William Clark, 14-6-84, 260 miles 14 laps." Also have a B&W pic of him on the bicycle. Poor gent looks a little like me! It has the very large wheel on the front, looks like a thin coat of solid rubber on the rim.
I've wondered how sore was his behind after the race!
