The trackbike site guy said it was made by a silk weaving company, and it has a butterfly design pinstripped on the seat tube. The tires have a raised motif which I can only guess is a mulberry leaf or flower garland. The "curb" here in Bergen Co. N.J. has been the the source of my last 3 dozen bikes used for rebuilds. I found this one
leaning on a dumpster waiting to be rescued. No one there, cleaning out a garage, knew any thing about its origins. I'd usually undertake its rehabilitation, but I think I'm going to offer it 'as is' on eBay, as my plate is really full. I'll need a week to write a decent description. Wish me luck.
