My Ireland section is woefully thin so to bump it up with a replica is a good move. Initially disappointed to find a replica I fired up eBay to find that that was exactly what I had bid upon!
This one is an Irish harp on a blue field with a green banner. It is deistinctive as a replica with its gold rather than silver metal and all in one modern style safety pin. The real giveaway are the words replica which are stamped upon it.
Maker unknown.
