They are 16.50 € each...the fox can be purchased HERE, and the bird HERE. The site is all in German, but I think it should be alright to navigate.
Thank you, Hungrrr Verlag!
EDIT: it has been brought to my attention that Dawanda (the site I linked to above) doesn't ship to the US. The plates are also available through http://hunger.bigcartel.com/ for $22.00 each, and can ship to the States. Perhaps it will be possible for me to order several at once and then sell them here - I am looking into it, so hold tight. I'll keep you updated!
