Provenance: Gareth Williams Chess Collection. This set features in Gareth's book: "Masterpieces", Apple Press, 2000, illustrated pp. 38-39:
For convenience all chessmen have been turned, the traditional horse's head for the knight being omitted, thereby saving the manufacturer the cost of employing a skilled carver. This is a typical French playing set of the eighteenth-century. The abstract design is very neutral, an astute marketing ploy so as not to discourage their sales to various continuously volatile political and religious factions within."
