This is the first wood card in my collection. I've seen these in various sets, but they're usually very low numbered and out of my price range. This one came pretty cheap since Gypsy Queen has been out a while and is off most collector's radar.
I assumed that the cards were on actual pieces of wood, with the picture etched in.
Just cardboard made to look like wood. Not sure what the big deal is.
This will finish off my Barney Gypsy Queen Rainbow with eight cards...
