Maybe my magnifying glass is not strong enough but only some parts of the clouds on one plate are similar to grid points. However, in my opinion they are not precise and regular enough. The darker parts and the snow seem hand-painted to me. I think I can see brushstrokes. Please do not understand me wrong. I am not interested in to find out the value of the plates, I just want to know more about their origins. Do you have an idea, where I can try to find out more?

Many thanks again and best regards

Many thanks for your information. I only have a question to your opinion that the plates are not painted by hand:
If thats the case, think I should be able to see a grid?
