Imay already know the answer to this, but I'm not 100% sure. I'm unwilling to influence your answers, so I'm saying nothing yet. What would you call these? For scale, I'll mention that plate is 28cm / 11 inches in diameter. No idea what size my hand is other than hand sized. Do hands get sized?
I don't know why that photograph is blurred on eG; it isn't on my computer. Still, it's only for scale, again.
