Ginnie Bamford (probably) Large Pottery Jug

Thought to be one of her early marks, but the representations of her marks in the BSPM book are very poor

Her earliest mark is supposed to be CP, but I've yet to see an example of it. It's possible this is an example of her CP mark, or it's gb. I assume she widened and added gb inside it in 1980 when she moved studios (and maybe because it looked too much like the St Ives stamp). She was certainly using the later gb stamp at the Sloop Craft Centre in the 80s. There's a similar example on the Ginnie Bamford thread which is dated 1978 when she was at Clock House Pottery.
