Small printed works consisting of one small-sized leaf of paper folded and not stitched or bound, containing printed matter, chiefly for gratuitous distribution
Small cards produced since the 19th century bearing the name and address of a business concern and one of its representatives, and intended more for information than advertisement. For small printed sheets or cards bearing tradesmen's advertisements from the 17th through the 19th century, use "trade cards." For cards made later and distributed for advertisement, use "advertising cards."
