Hi, I have one of these in my personal collection. Is there anything stamped on the back of this example? The one I have has a stamp on the back "Brigg's Booters" Abertillery, the ink stamp is in the glaze. I did research and couldn't find the Boot Shop in Abertillery until about 1912 and I just can't think why they would want to order pressings of this plate in-between anniversaries? Have you any ideas?
