Kennedy & Bragaw: English and American Hardware, 203 Main Street, Hartford, Ct, July 1st, 1845.
This firm was in business from 1844-1846. Before the advent of bound catalogs, merchants marketed their goods through sheet listings such as this one. Easily folded for mailing, in this early case as a stampless letter, the listing doubled as a format for personal correspondence between the seller and the prospective buyer.
At the bottom of the sheet is a note: "Joiners Planes of our own Manufacture". The proprietors in question were Leonard Kennedy, Jr. and Isaac Bragaw. To my knowledge, no imprint has been recorded. If you have a plane marked by this merchant partnership, please come forward."
