I'm not a huuuge fan of Jonathan Adler's designs ... but what I do like is finding examples of pieces on eBay, which when placed side-by-side, clearly show what he is inspired by!
The horse on the left is a piece of mid-century pottery I found on eBay. The horse on the right is a piece designed by Jonathan Adler.
I'm undecided as to which I like more. I love the variations in green and the "roughness" of the design of the original piece. But on the other hand, I really like the cleaned up lines and simple white of JA's design.
