I got the pocket size RWS included in the US Games "The Complete Tarot Kit". I wondered how they managed to make the two decks - the RWS and the Thoth in the same size, as they have different proportion (the Thoth is wider than the RWS with the same height). Then I noticed that the RWS deck's height is a bit "compressed" to get the proportion. This can be seen especially in the cards with big round elements - Wheel of Fortune, the Moon, the Sun - they are not perfect round, rather slightly oval. I am not sure if the separately sold pocket size edition is the same included in the kit. This is a bit displeasing though.
These are useful little decks to have though, very portable. The books are ok too but the tarot book confuses the Rider Waite/Thoth Kings.
