Today I received my Smith-Waite Centennial Tarot deck (I call it SWC13: and the deck in the earlier set SWC09).
Comparing them side by side, I noticed a verly slight difference. The thickness of SWC13 pack (78 cards) is 28mm while that of SWC09 is 29.2mm. And the color of 13 is, in my eyes, a bit brighter than the 09. The difference is really subtle. The photoshop sampling shows the yellow of SWC13 (taken from the inside of 0 in the FOOL) as R216-9, G167-196, and B40-49. The SWC09's yellow is R223-228, G178-198, and B23-40.
SWC13 has five extra cards, one with the title and the face of High Priestess, and four showing some of Pixie's artworks. The 36 pages LWB tells the background story of RWS, divinatory meanings of each card, and celtic cross spread. Honestly I'm quite satisfied with the deck.
