Sampler Featuring Illustrated Salt Glazed Motifs

I do a bit of ceramics and I think I know what they are referring to when they say this sampler is about Salt Glazed items, but I think it must have been a vintage trend of certain salt glazed items.  Because you can get far more colors in a "salt glaze" kiln that just white and grey.

But what matters here is that it is a beautiful sampler!
