I love these mystery deck threads; but in this case, I haven't the foggiest idea. I'm quite sure I've never seen this deck. I would most certainly remember a giant green "frog" climbing on the wheel of fortune!
Absolutely gorgeous deck. But alas, I also have no idea. It looks old, it could be a deck that is not really readily available. Lets hope Le Fanu or Gregory knows.
I have seen this deck on eBay or in a book and I cannot remember the name of it. I will keep looking. It is frustrating as I can almost remember the name/origin of it.
