Very nice. Also, if I am being very honest, as much as I like the card itself, it is not the best for a signature, in my personal opinion. The artowrk and color scheme is so crowded bottom right that it is hard to comprehend the signature. Maybe a different coloured pen would have popped the signature more?
Love this card. MC Escher is one on my all time favorite artist and Oswaldo Kato is one of my favorite Pokemon illustrators. It would be nice to have the signature pop more. If I were to do a Kato sig. this card would be high on the list of possibilities. Congratulations on a nice addition
