This lovely piece of ephemera bears no postcard markings, advertising or fine print information, so I'm thinking it was perhaps a freebie tucked inside a ladies' journal at the turn of the century? Whatever it is, it's deeply embossed and the colors still as pastel pretty as when printed. It is almost but not quite typical antique postcard size, about 3 and 6/16 by 5.5 inches. No creases; light foxing.
