These picture was taken by Peter Weigle, maybe you have heard of him, and there is a Peter Weigle bicycle in the background. In the foreground is a little bike, of unknown marque, that Curtis set up for his son-Curtis, the third. It as aluminum cottered cranks, fixed gear, and hand box-lining.
Notice the "C" on the fender, that's for Curtis, made from a bicycle spoke.
We added the Sun bicycle headbadge, because it is for Curtis's son. get it.
