Yes I have seen those before. Hard to get them here in the U.S. though. Here's my custom set.
Tournament Chess Piece Styles

I remember in Sevilla 1987 Karpov-Kasparov match they played with an Indajesa set (Spanish made) and, specially for the match, a special rook was made with the shape of a famous tower in Sevilla called "la torre del oro". Both players accepted this "diferent" rook but there was one piece that they didn't want to play with, and that was the knight. So the knight was replaced by the Staunton Europa of the same manufacturer that did look a little better for both players.
This is the rejected knight.
Do you know why they rejected to use our "beloved" Spanish Indajesa knight?
Woohoo! Awesome picture and set!
