I suppose there might be some criticism concerning this series, that it is repetitious.....that is is formulaic. It is and I do not apologize for that. Frequently a series is just that. There are similarities in each piece. I do not mind it. When you look at many artists work you see that they "practice" an idea. It was a fun series to do and a surprising one for me. I really had no interest in sumo wrestling but I sure like the idea behind the stand up sumo wrestler vintage cards that I discovered.
