Here are just a few "advertisements" for black goods, mourning calicoes, lawns and muslin etc. These are from the Library of Congress. If you have access to other newspaper data bases try the same term searches. Sometimes we have not "seen" an original object to document but reading period advertisements lets you "see" what was offered for sale.
