I'm not finding an exact match in the Engel guidebook (not surprising, it's extensive but new sets are ID'd regularly) but the back certainly indicates a Marusan issue from the late 50s thru 1962 or so. The scanned page below shows similar backs but more traditional Menko fronts from that era. There are many other Mansuran sets in the book with slight variations of these backs.
