This is a very pretty mysterious nappy.  It has a mark, but I have been unable to identify it.  It has a three lobed clover/shamrock with the letters “G”, “C” and “O” inside each of the lobes.  I have tried to show it in the second photo.

The larger photo does not indicate the attractiveness of this piece.

If anyone has any idea of the provenance of this piece I would be grateful for the information.
