It is mentioned in the product description that this is a small deck, but, if you are like me, you probably forgot to read it.
This deck is not the regular Marseilles deck, it is the deck 'restored' by Jodorowsky. I bought it because I bought his book 'The Way of Tarot'. The book has pictures of each of the restored cards in black and white (full page for the Major Arcana and four cards on slightly more than half a page for the Minor Arcana cards). The book also has a few pages in colour of the Major Arcana and the court cards, at the same size of the cards of this small deck. So, you do not really need to buy the deck to go with the book. But if you would like to see all the cards in colour, the deck is very useful.
The colouring of the deck is very different from that of the traditional Marseilles deck. Jodorowsky also added light blue, and light and dark green. It does brighten up the deck quite a bit (I never really liked the somewhat stern colours of the Marseilles tarot). This makes the deck a nice addition to the original Marseilles. I would not use this deck as a replacement of the Marseilles, though, because Jodorowsky's changes are highly personal.
