I live for the CABE
I checked my 1897 Sears & Roebuck Catalogue and of the Ladies' bicycle models offered that year; "Electric", "Utah", "Yukon", and the "Uno" which was the closest in design and construction to the "Alvah". Same style crank, pedals, frame, handle bar clamp, seat post, grips, etc. Based on the 1897 S&R offerings, I believe this "Alvah" must be either 1898 or 1899 because I also referenced my 1900 S&R catalog. The Ladies' bicycle models offered in 1900 were the; "Jewel", "Queen", and "Princess". The construction and componentry of the 1900 models had evolved just enough for me to conclude the "Alvah" predates 1900. Unfortunately I do not have S&R catalogues for 1898 or 1899 so I am unable to provide a copy of the advertisement for the "Alvah". This "Alvah" being offered for sale is certainly one of the finest examples of a truly preserved bicycle.
