Where can I find a reproduction of this set?

I'd like to get a quality reproduction of the famous Max Ernst chess set, but I haven't found any good sources. It looks like chessbazaar used to sell one, but the link I found didn't take me to anything useful.  If you know of a reliable seller, please post.  This is the set I'm referring to:

Thanks.

They appear from time to time, but it does appear that the Ernst estate are pretty active in enforcing their rights to the design, so they appear and then disappear.  There was an original sold by Sotheby's a few years ago, but they are genuinely expensive.   

Greg-

  Thanks for the info.  I did run across one Sotheby's auction from 2015 where an original Ernst set was expected to go for $5000-$7000...the final hammer price was $30,000. Yikes!  I'll keep looking for a reproduction.

I remember seeing one reproduction advertised a few years ago that claimed to come with extra queens, but in that set the king is the second tallest piece, so it actually came with extra kings which I thought was a nice touch.
