If an apology is needed for writing again on the subject of playing cards, the excuse may be offered that new lights have been turned on the subject, so that there is fresh information to lay before the public, derived from a close and exhaustive study of the European libraries and museums, as well as of the pictures on the Playing Cards themselves or prints found in those repositories, and also in the collection owned by the writer; for these speak their histories to those who regard their symbols with appreciative knowledge since they had an immense significance when originally adopted.
