Legend Arthurian : Stars on the Back?

Parzival

Does anyone know about the star patterns on the backs of Legend Arthurian Tarot? I just purchased an excellent condition 1996 set at a flea market, complete with celtic cross spread sheet, and I looked closely again at a fine deck of years before-- I have a later 2003 edition. The star patterns on the backs (same with both editions) look consciously done and not random. Also, taking out the two editions, 1996 and 2003, I noticed that the coloration is richer, stronger, much more vivid in the earlier edition, faded and muted in the later edition. Big difference. The early printing glows while the later printing shadows.
