Superb set of 3 with huge 'square'

Another exceptional set of counters. The large square is exactly that - one of the largest pieces of m-o-p made in to counters. Magnificent work from Canton!  Despite the wealth of armorial detail - crest arms and monogram, I failed to find its owner. I also suspect that  there would also have been another shape to the set - probably a round. But this is a superb museum-worthy set  -  or part-set!
